sata_sis: SCR accessors return -EINVAL when requested SCR isn't available
sis_scr_cfg_read() can't access SError and was incorrectly returning
-1 instead of -EINVAL. This went unnoticed because SError used to be
cleared in @postreset() and it didn't care about how scr_read() failed
but commit ac371987 moved SError clearing into sata_link_resume() and
SCR access failure other than -EINVAL is considered an error condition
and exposes the incorrect return value bug as detection failure. Fix
it.
Also, scsi_scr_cfg_write() was incorrectly returning 0 after it
ignored the request to write to SError. Make it also return -EINVAL.
This was bisected and reported by Patrick McHardy.
