Avi Kivity 6d0a2b5075 logalloc: don't invalidate merged region ...

A region being merged can still be in use; but after merging, compaction_lock
and the reclaim counter will no longer work.  This can lead to
use-after-compact-without-re-lookup errors.

Fix by making the source region be the same as the target region; they
will share compaction locks and reclaim counters, so lookup avoidance
will still work correctly.

Fixes #286.
