RDMA/bnxt_re: Fix a couple off by one bugs

BugLink: https://bugs.launchpad.net/bugs/1836287
[ 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.
