RDMA/cxgb3: Limit fast register size based on T3 limitations
T3 firmware only supports one WRs worth of page list for fast register work requests. The driver currently allows 2 WRs worth, which doesn't work for T3, so reduce the limit in the driver. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
