media: vimc: use new release op
Use the new v4l2_subdev_internal_ops release op to free the
subdev memory only when the last user closed the file handle.
Move v4l2_device_unregister_subdev() to the end of the
vimc_ent_sd_unregister() function since now the unregister_subdev()
call may free the vimc_ent_device struct which is used after the
unregister_subdev() call. So this now has to be done last.
