Subject: [PATCH] journal: make sure to initially populate the space info cache
 (#4807)

Make sure to populate the cache in cache_space_refresh() at least once
otherwise it's possible that the system boots fast enough (and the journal
flush service is finished) before the invalidate cache timeout (30 us) has
expired.

Fixes: #4790
(cherry picked from commit 3099caf2b5bb9498b1d0227c40926435ca81f26f)
