rpmsg: glink: Avoid infinite loop on intent for missing channel
[ Upstream commit 3e74ec2f39362bffbd42854acbb67c7f4cb808f9 ]
In the event that an intent advertisement arrives on an unknown channel
the fifo is not advanced, resulting in the same message being handled
over and over.
Fixes: dacbb35e930f ("rpmsg: glink: Receive and store the remote intent buffers")
