[PATCH 06/15] btrfs: sysfs, move add remove _mounted function together

[Anand Jain <anand.jain@oracle.com>]

The functions btrfs_sysfs_add_mounted() and btrfs_sysfs_remove_mounted()
which add and remove files and directory under /sys/fs/btrfs/UUID keep
them together to improve readability. No functional changes.
