[libvirt] [PATCH 14/22] util: Remove NONNULL(1) for virHostdevPrepareDomainDevices

[John Ferlan]

Since the code checks 'mgr == NULL' anyway, no need for the prototype
to have the NONNULL arg check.  Also add an error message to indicate what
the failure is so that there isn't a failed for some reason error.
