libata: add no penalty retry request for EH device handling routines

Let -EAGAIN from EH device handling routines trigger EH retry without
consuming its tries count.  This will be used to implement link SPD
horkage which requires hardreset to adjust SPD without affecting other
EH decisions.  As it bypasses the forward progress guarantee provided
by the tries count, the requester is responsible for ensuring forward
progress.
