[PATCH 12/15] btrfs: sysfs, unexport btrfs_sysfs_add_mounted()

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

In open_ctree() we call btrfs_sysfs_add_fsid() to create
/sys/fs/btrfs/UUID kobject, and in the following line of code in
open_ctree() we call btrfs_sysfs_add_mounted() to create its attributes.
And there is no other users of btrfs_sysfs_add_mounted(). So let
btrfs_sysfs_add_fsid() also create its attributes and make
btrfs_sysfs_add_mounted() a local static function.
