libata: unify mechanism to request follow-up SRST
Previously, there were two ways to trigger follow-up SRST from
hardreset method - returning -EAGAIN and leaving all device classes
unmodified. Drivers never used the latter mechanism and the only use
case for the former was when hardreset couldn't classify.
Drop the latter mechanism and let -EAGAIN mean "perform follow-up SRST
if classification is required". This change removes unnecessary
follow-up SRSTs and simplifies reset implementations.
