RDMA/bnxt_re: Fix a couple off by one bugs

Browse source 
[ Upstream commit 474e5a8606 ]

The sgid_tbl->tbl[] array is allocated in bnxt_qplib_alloc_sgid_tbl().
It has sgid_tbl->max elements.  So the > should be >= to prevent
accessing one element beyond the end of the array.

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