Fix CQE expansion of unsignaled WQE -- don't expand the CQE when the
WQE index of the completed CQE matches with last pending WQE (tail) in
the queue.

It looks like one check was accidentally duplicated, and the other 3
checks were left out. This was detected by scripts/coccinelle/tests/doubletest.cocci:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:895:6-54: duplicated argument to && or ||

We want to set attr->max_srq_sge to dev->attr.max_srq_sge, not to itself.

The dev->sgid_tbl[] array is allocated in ocrdma_alloc_resources().
It has OCRDMA_MAX_SGID elements so the test here is off by one.

The ocrdma_alloc_lkey() function never returns NULL pointers -- it
returns ERR_PTRs.

First, fix
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c: In function 'ocrdma_alloc_pd':
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:371:17: warning: 'dpp_page_addr' may be used uninitialized in this function [-Wuninitialized]
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:337:6: note: 'dpp_page_addr' was declared here
which seems that it may border on a bug (the call to ocrdma_del_mmap()
might conceivably do bad things if pd->dpp_enabled is not set and
dpp_page_addr ends up with just the wrong value).
Also take care of:
drivers/infiniband/hw/ocrdma/ocrdma_hw.c: In function 'ocrdma_init_hw':
drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2587:5: warning: 'status' may be used uninitialized in this function [-Wuninitialized]
drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2549:17: note: 'status' was declared here
which is only real if num_eq == 0, which should be impossible.
