[infiniband] Return status code from ib_create_cq() and ib_create_qp()
Any underlying errors arising during ib_create_cq() or ib_create_qp()
are lost since the functions simply return NULL on error. This makes
debugging harder, since a debug-enabled build is required to discover
the root cause of the error.
Fix by returning a status code from these functions, thereby allowing
any underlying errors to be propagated.
