Default scsi_dh_rdac: Adding the match function for rdac device handler

This patch introduces the match function for rdac device handler. Without this,
sometimes handler attach fails during the device_add. Included check for TPGS
bit before proceeding further. The match function was introduced by this patch

As the real patch of checking VPD pages is a bit more involved (eg
we're taking the lock during ->match(), so invoking any I/O from
here will get tricky), it's a sensible interim solution.
