rpmsg: glink: Release driver_override
[ Upstream commit fb80ef67e8ff6a00d3faad4cb348dafdb8eccfd8 ]
Upon termination of the rpmsg_device, driver_override needs to be freed
to avoid leaking the potentially assigned string.
Fixes: 42cd402b8fd4 ("rpmsg: Fix kfree() of static memory on setting driver_override")
Fixes: 39e47767ec9b ("rpmsg: Add driver_override device attribute for rpmsg_device")
