[libvirt] [PATCHv2 10/10] virterror: clean up VIR_ERR_INVALID_INTERFACE usage



* src/util/virterror.c (virErrorMsg): Unify semantics.
* src/libvirt.c (virLibInterfaceError): Convert to macro, and drop
extra parameter.  All callers simplified.
(virLibInterfaceErrorHelper): Refactor function to take new
parameters.
---

There's still more that can be cleaned up, but I ran out of time
on this patch series today and thought I'd at least get this much
posted (and possible some of the earlier patches pushed, if they
get an ACK).
