IB/rdmavt: Allocate CQ memory on the correct node
[ 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.
