clear_prefree_segments() issues small discards after discarding full segments. These small discards may not be section aligned, so not zone aligned on a zoned block device, causing __f2fs_iissue_discard_zone() to fail. Fix this by not issuing small discards for a volume mounted with the BLKZONED feature enabled.
