libata: ignore recovered PHY errors

No reason to get overzealous about recovered comm and data errors.
Some PHYs habitually sets them w/o no good reason and being draconian
about these soft error conditions doesn't seem to help anybody.

If need ever rises, we might need to add soft PHY error condition, say
AC_ERR_MAYBE_ATA_BUS and use it only to determine whether speed down
is necessary but I don't think that's very likely to happen.  It's far
more likely we'll get timeouts or fatal transmission errors if
recovered errors are so prominent that they hamper operation.
