multidevice support for check_mounted
Check_mount() should also work with multi device filesystems. This patch adds checks that allow to detect if a file is a device file used by a mounted single or multi device btrfs or if it is a regular file used by a loopback device that is part of a mounted single or multi device btrfs. The single device checks also work for non-btrfs filesystems. This might be helpful to prevent users from running btrfs programs (e.g. mkfs.btrfs) accidentally on a filesystem used somewhere else.
