libata: always do follow-up SRST if hardreset returned -EAGAIN
As an optimization, follow-up SRST used to be skipped if
classification wasn't requested even when hardreset requested it via
-EAGAIN. However, some hardresets can't wait for device readiness and
skipping SRST can cause timeout or other failures during revalidation.
Always perform follow-up SRST if hardreset returns -EAGAIN. This
makes reset paths more predictable and thus less error-prone.
While at it, move hardreset error checking such that it's done right
after hardreset is finished. This simplifies followup SRST condition
check a bit and makes the reset path easier to modify.
