libata: move PMP SCR access failure during reset to ata_eh_reset()
If PMP fan-out reset fails and SCR isn't accessible, PMP should be
reset. This used to be tested by sata_pmp_std_hardreset() and
communicated to EH by -ERESTART. However, this logic is generic and
doesn't really have much to do with specific hardreset implementation.
This patch moves SCR access failure detection logic to ata_eh_reset()
where it belongs. As this makes sata_pmp_std_hardreset() identical to
sata_std_hardreset(), the function is killed and replaced with the
standard method.
