s390/hypfs: avoid error message under KVM

When booting under KVM the following error messages are issued:

hypfs.7f5705: The hardware system does not support hypfs
hypfs.7a79f0: Initialization of hypfs failed with rc=-61

Demote the severity of first message from "error" to "info" and issue
the second message only in other error cases.
