Valid id checking for callbackmsg[id]).row_mode in process()

In VIDDEC3_process or VIDENC2_process, if low latency is used, then
id will have a valid value of >= 0.
When full frame is used, after process call, there is a condition
check of callbackmsg[id]).row_mode. Problem is that id might not be valid
for full frame. With id value < 0, the value in callbackmsg[id]).row_mode
can be guarantee to be correct. Issue is found when id = -1 and the value
of callbackmsg[-1]).row_mode points to less than 0, which causes the
condition to pass.

This commit is fixing the issue by adding additional check to make sure
id is >= 0 when calling callbackmsg[id]).row_mode so that the
condition check will be valid to determine low latency mode or full
frame mode after process().
