IB/mthca: Correct reported SRQ size in MemFree case.
MemFree devices need to reserve one shared receive queue (SRQ) work request for internal use, so the capacity returned from the create_srq and query_srq methods should be srq->max - 1. Signed-off-by: Dotan Barak <dotanb@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
