media: v4l: subdev: Also return pads array information on stream functions

There are two sets of functions that return information from sub-device
state, one for stream-unaware users and another for stream-aware users.
Add support for stream-aware functions to return format, crop and compose
information from pad-based array that are functionally equivalent to the
old, stream-unaware ones.

Also check state is non-NULL, in order to guard against old drivers
potentially calling this with NULL state for active formats or selection
rectangles.
