[ Upstream commit db9a2c6f9b6196b889b98e961cb9a37617b11ccf ]
CQ allocation does not ensure that completion queue entries and the completion queue structure are allocated on the correct numa node.
Fix by allocating the rvt_cq and kernel CQ entries on the device node, leaving the user CQ entries on the default local node. Also ensure CQ resizes use the correct allocator when extending a CQ.
