RDMA/cxgb3: Support for new abort logic

The HW now posts 2 ABORT_RPL and/or PEER_ABORT_REQ messages.  We need
to handle them by silenty dropping the 1st but mark that we're ready
for the final message.  This plugs some close races between the uP and
HW.  Also update the minimum required firmware version.
