[PATCH] conf: Adjust hyperv tlbflush formatting

Commi 247357cc292a added support for direct and extended modes for tlbflush, but forgot to do the formatting as well. Instead of rewriting the whole hyperv feature formatting to use yet another attribute and child buffers, just fix it in a way the other features are and leave the refactoring to later. One reason for that is that we should fix this ASAP since without this patch the features will be stripped when formatting the XML on the disk and lost after next daemon reload.
