[PATCH v3 02/29] media: v4l2-subdev: Align frame descriptor error codes with routing

[Sakari Ailus <sakari.ailus@linux.intel.com>]

__v4l2_subdev_get_frame_desc_passthrough() returns -ENOSPC when there are
too many routes. There's a subtle difference when compared to -E2BIG, but
-E2BIG can be used in this case as well. In practice this was unlikely to
having been ever returned from the kernel as things currently stand.

Align the error codes with the routing IOCTLs.
