libata: fix n_sectors failure handling during revalidation
If revalidation fails because device has different n_sectors after
configuration the original n_sectors should be restored before failing
revalidation. Without this fix, n_sectors difference will incorrectly
and silently pass revalidation when revalidation is retried.
