USB: keyspan: fix NULL-pointer dereferences and memory leaks
Fix NULL-pointer dereference at release by moving port data allocation
and deallocation to port_probe and port_remove.
Fix NULL-pointer dereference at disconnect by stopping port urbs at
port_remove.
Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer accessible at
disconnect or release.
Note that this patch also fixes port and interface-data memory leaks in
the error path of attach should port initialisation fail for any port.
Compile-only tested.
