hwrng: ks-sa - Fix runtime PM cleanup on registration failure

Browse source

ks_sa_rng_probe() enables runtime PM and resumes the device before
registering the hwrng. If devm_hwrng_register() fails, probe returns
without dropping the runtime PM usage count or disabling runtime PM.

Unwind the runtime PM state on the registration failure path, matching
the cleanup done by remove().
