RDMA/bnxt_re: Fix max_qp_wrs reported

Browse source

[ Upstream commit 40be32303e ]

While creating qps, driver adds one extra entry to the sq size
passed by the ULPs in order to avoid queue full condition.
When ULPs creates QPs with max_qp_wr reported, driver creates
QP with 1 more than the max_wqes supported by HW. Create QP fails
in this case. To avoid this error, reduce 1 entry in max_qp_wqes
and report it to the stack.
