Subject: [PATCH 1/3] misc: fastrpc: Deregister device nodes properly in error scenarios

From: Anandu Krishnan E <quic_anane@...cinc.com>

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.

Fixes: 3abe3ab3cdab ("misc: fastrpc: add secure domain support")
