RDMA/bnxt_re: synchronize the qp-handle table array
There is a race between the CREQ tasklet and destroy qp when accessing the
qp-handle table. There is a chance of reading a valid qp-handle in the
CREQ tasklet handler while the QP is already moving ahead with the
destruction.
Fixing this race by implementing a table-lock to synchronize the access.
