Commit c22a03454 QAPIfied option parsing in the NFS block driver, but
forgot to remove all the options we processed. Therefore, we get an
error in bdrv_open_inherit(), which thinks the remaining options are
invalid. Trying to open an NFS image will result in an error like this:
Block protocol 'nfs' doesn't support the option 'server.host'
Remove all options from the QDict to make the NFS driver work again.
