Stefano Garzarella 0bde59c172 vhost-vdpa: set v->config_ctx to NULL if eventfd_ctx_fdget() fails ...

In vhost_vdpa_set_config_call() if eventfd_ctx_fdget() fails the
'v->config_ctx' contains an error instead of a valid pointer.

Since we consider 'v->config_ctx' valid if it is not NULL, we should
set it to NULL in this case to avoid to use an invalid pointer in
other functions such as vhost_vdpa_config_put().
