RDMA/bnxt_re: Fix the locking while accessing the QP table
QP table handling is synchronized with destroy QP and Async
event from the HW. The same needs to be synchronized
during create_qp also. Use the same lock in create_qp also.
Fixes: 76d3ddff7153 ("RDMA/bnxt_re: synchronize the qp-handle table array")
Fixes: f218d67ef004 ("RDMA/bnxt_re: Allow posting when QPs are in error")
Fixes: 84cf229f4001 ("RDMA/bnxt_re: Fix the qp table indexing")
