Subject: [PATCH] qemuDomainAttachRNGDevice: do not access source.file randomly

We pass the source.file to qemuCheckCCWS390AddressSupport for
the purpose of reporting an error message without actually checking
that the rng device is of type VIR_DOMAIN_RNG_BACKEND_RANDOM.

Change it to a hardcoded "rng" string, which also avoids
referring to the device by a host-side attribute.
