maint: clean up error reporting in migration
The choice of error message and category was not consistent in the migration code; furthermore, the use of virLibConnError is no longer necessary now that we have a generic virReportError. * src/qemu/qemu_migration.c (virDomainMigrate*): Prefer virReportError over virLibConnError.
