greybus: bundle: use kstrdup() for state file

Browse source

The kernfs code guarantees we'll get a NUL-terminated buffer.
Use kstrdup() rather than kzalloc() + memcpy() in state_store()
making it slightly clearer what we're doing.  This has the added
benefit of guaranteeing that the stored string has no NUL character
inside it.
