d402b6a21a825a5c07aac9251990860723d49f5d qemu-img: Recognize no creation support in -o help
The only users of print_block_option_help() are qemu-img create and
qemu-img convert for the output image, so this function is always used
for image creation (it used to be used for amendment also, but that is
no longer the case).
So if image creation is not supported by either the format or the
protocol, there is no need to print any option description, because the
user cannot create an image like this anyway.
This also fixes an assertion failure:
$ qemu-img create -f bochs -o help
Supported options:
qemu-img: util/qemu-option.c:219:
qemu_opts_print_help: Assertion `list' failed.
[1] 24831 abort (core dumped) qemu-img create -f bochs -o help
