[PATCH v3 7/8] vhost: enable log_shmfd protocol feature

From: Yuanhan Liu <hidden>
Date: 2016-01-29 04:57:32
Subsystem: library code, the rest · Maintainers: Andrew Morton, Linus Torvalds

To claim that we support vhost-user live migration support:
SET_LOG_BASE request will be send only when this feature flag
is set.

Besides this flag, we actually need another feature flag set
to make vhost-user live migration work: VHOST_F_LOG_ALL.
Which, however, has been enabled long time ago.
