btrfs-progs: refine btrfs-debug-tree error prompt when a mount point given
Now, if exec:
# btrfs-debug-tree <mount_point>
it echos:
: Superblock bytenr is larger than device size
But it is quite misleading, because it is a valid btrfs.
In this case, we should tell the developer to provide a block device.
After apply:
: '<mount_point>' is not a block device
