From: Dan Carpenter <dan.carpen...@oracle.com>
[ Upstream commit 474e5a86067e5f12c97d1db8b170c7f45b53097a ]
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: 1ac5a4047975 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
