Honor port_num while resolving GID for IB link layer in ibcore.

Browse Source 
ah_attr contains the port number to which cm_id is bound. However, while
searching for GID table for matching GID entry, the port number is
ignored.

This could cause the wrong GID to be used when the ah_attr is converted to
an AH.
