Do not set precommitted flag in cache when precommitted metadata does not exist.

Do not set precommitted flag in cache when precommitted metadata does not exist.

The use_precommitted flag indicates, that we want to use precommitted metadata
(used in suspend call to preload table with precommitted data).

But if there are no such data, committed metadata are read but the cache
still contains that precommitted flag.

(The problem is that later possible drop_metadata call will not invalidate
device in cache.)

The wrong precommitted state is stored in on remote nodes during normal
suspend/resume cycle _without_ vg_write/commit.

Use the PRECOMMITTED status flag here instead (which is always set if using
precommited metadata here).
