libata-pmp-prep: add @new_class to ata_dev_revalidate()
Consider newly found class code while revalidating. PMP resetting
always results in valid class code and issuing PMP commands to
ATA/ATAPI device isn't very attractive. Add @new_class to
ata_dev_revalidate() and check class code for revalidation.
