Btrfs: clear compress-force when remounting with compress option
Steps to reproduce:
# mkfs.btrfs -f /dev/sdb
# mount /dev/sdb /mnt -o compress-force=lzo
# mount /dev/sdb /mnt -o remount,compress=zlib
# cat /proc/mounts
Remounting from compress-force to compress could not clear compress-force
option. The problem is there is no way for users to clear compress-force
option separately.
Fix this problem by clearing @FORCE_COMPRESS flag when remounting to
compress=xxx.
