RDMA/bnxt_re: Optimize bnxt_qplib_get_dev_attr function
Optimize bnxt_qplib_get_dev_attr() by separating out query_version which
uses creq notification method to host. Due to serialization of cmdq by
firmware, expected latency in response to heavy multi-threaded rdma
applications might be observed.
This patch separates the version_query logic out of device attribute
query and called only during rdma driver init.
