Subject: [PATCH 2/4] media: visl: Hook the (TRY_)DECODER_CMD stateless ioctls

The (TRY_)DECODER_CMD ioctls are used to support flushing when holding capture
buffers is supported. This is the case of this driver but the ioctls were never
hooked to the ioctl ops.

Add them to correctly support flushing.

Fixes: 0c078e310b6d ("media: visl: add virtual stateless decoder driver")
