rpmsg: mtk_rpmsg: Fix circular locking dependency
During execution of the worker that's used to register rpmsg devices
we are safely locking the channels mutex but, when creating a new
endpoint for such devices, we are registering a IPI on the SCP, which
then makes the SCP to trigger an interrupt, lock its own mutex and in
turn register more subdevices.
This creates a circular locking dependency situation, as the mtk_rpmsg
channels_lock will then depend on the SCP IPI lock.

rpmsg: Avoid double-free in mtk_rpmsg_register_device

mtk_rpmsg_release

If rpmsg_register_device fails, it will call
mtk_rpmsg_release_device which already frees mdev.
