migration: Non multifd migration don't care about multifd flushes
RDMA was having trouble because
migrate_multifd_flush_after_each_section() can only be true or false,
but we don't want to send any flush when we are not in multifd
migration.
CC: Fabiano Rosas <farosas@suse.de
Fixes: 294e5a4034e81 ("multifd: Only flush once each full round of memory")
