rbd: Fix to cleanly reject -drive without pool or image
qemu_rbd_open() neglects to check pool and image are present. Missing
image is caught by rbd_open(), but missing pool crashes. Reproducer:
$ qemu-system-x86_64 -nodefaults -drive driver=rbd,id=rbd,image=i,...
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid
Aborted (core dumped)
where ... is a working server.0.{host,port} configuration.
Doesn't affect -drive with file=..., because qemu_rbd_parse_filename()
always sets both pool and image.
Doesn't affect -blockdev, because pool and image are mandatory in the
QAPI schema.
Fix by adding the missing checks.
