ext4: drop fast_commit from /proc/mounts
The options in /proc/mounts must be valid mount options --- and
fast_commit is not a mount option. Otherwise, command sequences like
this will fail:
# mount /dev/vdc /vdc
# mkdir -p /vdc/phoronix_test_suite /pts
# mount --bind /vdc/phoronix_test_suite /pts
# mount -o remount,nodioread_nolock /pts
mount: /pts: mount point not mounted or bad option.
And in the system logs, you'll find:
EXT4-fs (vdc): Unrecognized mount option "fast_commit" or missing value
Fixes: 995a3ed67fc8 ("ext4: add fast_commit feature and handling for extended mount options")
