When a failure occurs in rproc_add() it returns an error, but does
not cleanup after itself. This change adds the failure path in such

Why is this needed for stable kernels? And again, a Fixes: tag?
Patch 2 and patch 3 are leading up to fix rproc_add()
in case of a failure. This means we'll have errors with
use after free unless we call device_del() or cdev_del(),
also the sysfs and devtempfs nodes will also not be
removed.
Thanks,
