libata: hardreset on SERR_INTERNAL
There was a rare report where SB600 reported SERR_INTERNAL and SRST couldn't get it out of the failure mode. Hardreset on SERR_INTERNAL. As the problem is intermittent, whether this fixes the problem or not hasn't been verified yet, but hardresetting the channel on internal error is a good idea anyway.
