qemu-img: Fix crash in amend invocation
Example: $ ./qemu-img create -f qcow2 /tmp/t.qcow2 64M $ ./qemu-img amend -f qcow2 -o backing_file=/tmp/t.qcow2, -o help \ /tmp/t.qcow2 This should not crash. This actually is tested by iotest 082, but not caught due to the segmentation fault being silent (which is something that needs to be fixed, too).
