btrfs-progs: limit minimal num of args for btrfs-image
The btrfs-image requires at least 2 args to run, one for the source dev/file, the other for the target dev/file. This patch depends on patch: btrfs-progs: move the check_argc_* functions into utils.c Signed-off-by: Gui Hecheng <guihc.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz>
