[PATCH] rpmsg: glink: Remove channel decouple from rpdev release

From: Chris Lew
Date: Tue Oct 08 2019 - 21:34:21 EST

If a channel is being rapidly restarted and the kobj release worker is
busy, there is a chance the the rpdev_release function will run after
the channel struct itself has been released.

There should not be a need to decouple the channel from rpdev in the
rpdev release since that should only happen from the channel close
