offload ib subnet manager port and node get info query handling.

This change offloads ib subnet manager port and node get info query
handling to the HCA firmware to answer them. These port and node get
info query responses are time bound and HOST based sma software handler
responses can get delayed because of busy CPUs (RT workloads, interrupt
handlers, etc). Delayed responses can lead to SM taking node out of the
fabric which is not desirable. The port/node INFO query offload, will
let these specific SM queries handled by HCA firmware in a timely manner
irrespective of CPUs being busy at that moment in time.
