Tomasz Grabiec 79935df959 commitlog: replay: Respect back-pressure from memtable space to prevent OOM ...

Commit log replay was bypassing memtable space back-pressure, and if
replay was faster than memtable flush, it could lead to OOM.

The fix is to call database::apply_in_memory() instead of
table::apply(). The former blocks when memtable space is full.

Fixes #4982.

Tests:
  - unit (release)
  - manual, replay with memtable flush failin and without failing
