[PATCH v3] misc: fastrpc: Deregister device nodes properly in error scenarios

[Anandu Krishnan E]

During fastrpc_rpmsg_probe, if secure device node registration
succeeds but non-secure device node registration fails, the secure
device node deregister is not called during error cleanup. Add proper
exit paths to ensure proper cleanup in case of error.
