rpmsg: glink: Fix missing mutex_init() in qcom_glink_alloc_channel()

[ Upstream commit fb416f69900773d5a6030c909114099f92d07ab9 ]

qcom_glink_alloc_channel() allocates the mutex but not initialize it.
Use mutex_init() on it to initialize it correctly.

This is detected by Coccinelle semantic patch.
