Btrfs-progs: add btrfs device ready command

This command will be used by things like dracut that wish to know very
simply if all of the devices have been added to the kernel cache yet for the
device to be fully mounted.  This keeps initrd's from constantly having to
try to mount the file system until it succeeds every time a device is added
to the system.  Thanks,
