libata: skip EH autopsy and recovery during suspend
commit e2f3d75fc0e4a0d03c61872bad39ffa2e74a04ff upstream.
For some mysterious reason, certain hardware reacts badly to usual EH
actions while the system is going for suspend. As the devices won't
be needed until the system is resumed, ask EH to skip usual autopsy
and recovery and proceed directly to suspend.
