Clean up user_exp_rcv.c file by moving structure definitions into header
file user_exp_rcv.h. Since these structure definitions depend on the
structure definitions in mmu_rb.h, move #include "mmu_rb.h" above
the include "user_exp_rcv.h" or include of header files that include
user_exp_rcv.h

num_user_pages() function has been defined in both user_exp_rcv.c file
and user_sdma.c file. Move the function definition to a header file so
there is only one definition in the source repo.

Clean up hfi1_user_exp_rcv_setup function by moving page pinning and
unpinning related code to separate functions. In order to reduce the
number of parameters passed between functions, a new data structure
struct tid_user_buf is defined and used.

The allocate_ctxt() function adds the context to the fd data structure.
Since the context is not completely initialized, this can cause confusion
as to whether the context is valid or not.
Move the fd reference from allocate_ctxt() to setup_base_ctxt().
Update the necessary functions to be aware of this move.

Context initialization mixes base context init with sub context init.
This is bad because contexts can be reused, and on reuse, reinit things
that should not re-initialized.
Normalize comments and function names to refer to base context and
sub context (not main, shared or slaves).
Separate the base context initialization from sub context initialization.
hfi1_init_ctxt() cannot return an error so changed to a void and remove
error message.

Since almost all functions that use the hfi1_filedata get the pointer
from the file pointer, simplify by only passing the hfi1_filedata pointer.

The only context that frees user_exp_rcv data structures is the last
context closed (from a sub-context set). This leaks the allocations
from the other sub-contexts. Separate the common frees from the
specific frees and call them at the appropriate time.
Using KEDR to check for memory leaks we get:
Before test:
[leak_check] Possible leaks: 25
After test:
[leak_check] Possible leaks: 31 (6 leaked data structures)
After patch applied (before and after test have the same value)
[leak_check] Possible leaks: 25
Each leak is 192 + 13440 + 6720 = 20352 bytes per sub-context.

The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
