libata: mask swap internal and hardware tag
hen we're comparing the hardware completion mask passed in from the driver with the internal tag pending mask, we need to account for the fact that the internal tag is different from the hardware tag. If not, then we can end up either prematurely completing the internal tag (since it's not set in the hw mask), or simply flag an error: ata2: illegal qc_active transition (100000000->00000001) If the internal tag is set, then swap that with the hardware tag in this case before comparing with what the hardware reports.
