[libvirt] [PATCH 6/9] conf: make error returns from virDomainActualNetDefFormat consistent

[Laine Stump]

There was an error: label that simply did "return ret", but ret was
defaulted to -1, and was never used other than setting it manually to
0 just before a non-error return. Aside from this, some of the error
return paths used "goto error" and others used "return ret".

This patch removes ret and the error: label, and makes all error
returns just consistently do "return -1".
