Subject: [PATCH] nfs: Remove processed options from QDict

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.
