block/rbd: remove processed options from qdict

Commit 4bfb274 added some QAPIfication of option parsing in
qemu_rbd_open().  We need to remove all the options we processed,
otherwise in bdrv_open_inherit() we will think the remaining options are
invalid.

(This needs to go in 2.12 to avoid a regression that prevents rbd
from being opened.)
