video: driver: fix enc drain and change frame rate set handling

- Move driver to MSM_VIDC_DRAIN state when drain command
  is receieved for an encoder session
- Static HFI_PROP_FRAME_RATE setting to video fw handling
  is moved to inst database set function via
  msm_vidc_set_v4l2_properties to avoid enc session failure
  due to setting HFI_PROP_FRAME_RATE before starting video fw
