IB/mthca: Check alternate P_Key index when setting alternate path
Check that the alternate P_Key index is in range when setting the alternate path for a QP. Also make a cosmetic touch up to the debug message printed when the main P_Key index is out of range. Signed-off-by: Dotan Barak <dotanb@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
