hwrng: pseries - Return errors to upper levels in pseries-rng.c

commit d319fe2a0af3509f959d5195fb8916accbf14857 upstream.

We don't expect to get errors from the hypervisor when reading the rng,
but if we do we should pass the error up to the hwrng driver. Otherwise
the hwrng driver will continue calling us forever.
