media: stm32: dcmi: Fix subdev op call with uninitialized state
stm32-dcmi calls its source subdev with v4l2_subdev_call() using a
v4l2_subdev_state constructed on stack. This means that init_cfg is
never called for that state, and a source subdev that depends on the
init_cfg call may break.
A new macro has been added for this particular purpose, which properly
initializes the state, so let's use v4l2_subdev_call_state_try() here.
