soc: qcom: glink: Check for NULL transmissions



The G-Link core currently assumes that no NULL transmissions will be
sent. However, this is not the case - NULL transmissions are
encountered, but G-Link does not support them.

Modify the core to reject NULL transmissions by returning -EINVAL
when one is encountered.
