qemu-img: Check create_opts before image creation

If a driver supports image creation, it needs to set the .create_opts
field. We can use that to make sure .create_opts for both drivers
involved is not NULL for the target image in qemu-img convert, which is
important so that the create_opts pointer in img_convert() is not NULL
after the qemu_opts_append() calls and when going into
qemu_opts_create().
