misc: fastrpc: Fix an error handling path in fastrpc_rpmsg_probe()
If of_platform_populate() fails, some resources need to be freed as already
done in the other error handling paths.
Fixes: 278d56f970ae ("misc: fastrpc: Reference count channel context")
Fixes: 3abe3ab3cdab ("misc: fastrpc: add secure domain support")
