That was introduced by commit 77a4229719e511a0d38d9c355317ae1469adeb54
[SCSI] Retry commands with UNIT_ATTENTION sense codes to fix ext3/ext4 I/O error

discards as FS requests I think it should be reverted, preferably
already during this cycle, in which the patches to send these requests
as FS type were added.
