f2fs: Do not issue small discards in LFS mode 



commit acfd2810c75b0625897fc119a2d3a9c26cc0e405 upstream.

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.
