The nfs protocol driver is capable of creating images, but did not
specify any creation options. Fix it.
A way to test this issue is the following:
$ qemu-img create -f nfs nfs://127.0.0.1/foo.qcow2 64M
Without this patch, it segfaults. With this patch, it does not. However,
this is not something that should really work; qemu-img should check
whether the parameter for the -f option (and -O for convert) is indeed a
format, and error out if it is not. Therefore, I am not making it an
iotest.
