[PATCH v2 5/7] drm: writeback: Modify params for drm_writeback_get_out_fence

[Suraj Kandpal <suraj.kandpal@intel.com>]

Use drm_connector instead of drm_writeback_connector since it now
resides within drm_connector and also helps make sure
drm_wrtieback_connector is being modified mostly by drm core
provided helpers.

V1 -> V2: Use &connector->writeback (Dmitry)
