media: mediatek: vcodec: fix resource leaks in vdec_msg_queue_init()

Browse source

If we encounter any error in the vdec_msg_queue_init() then we need
to set "msg_queue->wdma_addr.size = 0;".  Normally, this is done
inside the vdec_msg_queue_deinit() function.  However, if the
first call to allocate &msg_queue->wdma_addr fails, then the
vdec_msg_queue_deinit() function is a no-op.  For that situation, just
set the size to zero explicitly and return.

There were two other error paths which did not clean up before returning.
Change those error paths to goto mem_alloc_err.
