virDomainNetDefParseXML: Fix error message for unknown value of //mac/@type

In v6.6.0-rc1~124 we've introduced a new mechanism for MAC
addresses for ESX: ignore all checks (type='static') that libvirt
or ESX would do (and possibly fail) for specified MAC address.
Accepted values for the @type attribute are "generated" and
"static". But the error message mentions a different attribute.
