Fix messages using VIR_ERR_XML_ERROR

This error code has existed since the dawn of time, yet the messages it
generates are almost universally busted. Here's a small sampling:

src/conf/domain_conf.c:4889 : XML description for missing root element is not well formed or invalid
src/conf/domain_conf.c:4951 : XML description for unknown device type is not well formed or invalid
src/conf/domain_conf.c:5460 : XML description for maximum vcpus must be an integer is not well formed or invalid
src/conf/domain_conf.c:5468 : XML description for invalid maxvcpus %(count)lu is not well formed or invalid

Fix up the error code to instead be

XML error: <msg>

Adjust the few locations that were using the original correctly (or shouldn't
have been using the error code at all).

v2:
    Fix wording of error code without a passed argument
