sparc: refactor code in fault_32.c
The sparc allmodconfig build broke due to enabling of the
branch_tracer that does some very clever things with
all if conditions. This caused my gcc 3.4.5 to be so confused that
it emitted a warning:
arch/sparc/mm/fault_32.c: In function `do_sparc_fault':
arch/sparc/mm/fault_32.c:176: warning: 'fixup' might be used uninitialized in this function
And with -Werror this broke the build.
Refactor code so it:
1) becomes more readable
2) no longer emit a warning with the branch_tracer enabled
