RDMA/bnxt_re: Fix a bunch of off by one bugs in qplib_fp.c

The srq->swq[] is allocated in bnxt_qplib_create_srq().  It has
srq->hwq.max_elements elements so these tests should be > instead of >=
or we might go beyond the end of the array.

Fixes: 1ac5a40479 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
