V4L2Decoder: do not check for DRC for secure codec

It's not possible to access the frame data if the secure codec is used.

An attempt to map() such data will result in an error, and attempt to
wait for the DRC will cause a nullptr dereference.

This patch adds a workaround, which skips the DRC verification if the
secure codec is used.
