Sakari Ailus 8ecd1db58b media: v4l: subdev: Fail graciously when getting try data for NULL state 
[ Upstream commit 2ba3e38517 ]

The state argument for the functions for obtaining various parts of the
state is NULL if it is called by drivers for active state. Fail graciously
in that case instead of dereferencing a NULL pointer.
