btrfs-progs: use check_argc_* to check arg number for all tools
Since this patch:
btrfs-progs: move the check_argc_* functions into utils.c
All tools including the independent tools(e.g. btrfs-image, btrfs-convert)
can share the convenience of the check_argc_* functions, so this patch
adopt the argc check functions globally.
