ata_std_prereset — prepare for reset

struct ata_link * link
ATA link to be reset
unsigned long deadline
deadline jiffies for the operation
link
is about to be reset. Initialize it. Failure from
prereset makes libata abort whole reset sequence and give up
that port, so prereset should be best-effort. It does its
best to prepare for reset sequence but if things go wrong, it
should just whine, not fail.
