RDMA/bnxt_re: Fix to export port num to ib_query_qp

Browse Source 
[ Upstream commit 34db8ec931b84d1426423f263b1927539e73b397 ]

Current driver implementation doesn't populate the port_num
field in query_qp. Adding the code to convert internal firmware
port id to ibv defined port number and export it.
