Tomasz Grabiec 870e9e5729 lsa: Replace compaction_lock with broader reclaim_lock ...

Disabling compaction of a region is currently done in order to keep
the references valid. But disabling only compaction is not enough, we
also need to disable eviction, as it also invalidates
references. Rather than introducing another type of lock, compaction
and eviction are controlled together, generalized as "reclaiming"
(hence the reclaim_lock).
