media: tegra-video: Fix memory leak in __tegra_channel_try_format()

In the Linux kernel, the following vulnerability has been resolved:

media: tegra-video: Fix memory leak in __tegra_channel_try_format()

The state object allocated by __v4l2_subdev_state_alloc() must be freed
with __v4l2_subdev_state_free() when it is no longer needed.

In __tegra_channel_try_format(), two error paths return directly after
v4l2_subdev_call() fails, without freeing the allocated 'sd_state'
object. This violates the requirement and causes a memory leak.

Fix this by introducing a cleanup label and using goto statements in the
error paths to ensure that __v4l2_subdev_state_free() is always called
before the function returns.
