Third time fooled by ATTRIBUTE_UNUSED. xenDaemonDomainCoreDump
understands VIR_DUMP_LIVE and VIR_DUMP_CRASH.

This breaks virDomainMigrate, because *DomainMigratePrepare is called
with the flags passed to virDomainMigrate, even if
xenDaemonDomainMigratePrepare doesn't use this flags it has to accept
all flags that the Xen driver understand in general form migration.
A quick grep for VIR_MIGRATE_ shows that those are at least
VIR_MIGRATE_LIVE
VIR_MIGRATE_PERSIST_DEST
VIR_MIGRATE_UNDEFINE_SOURCE
VIR_MIGRATE_PAUSED
