Fixed bug in Archive with insert delayed

Browse Source 
storage/archive/ha_archive.cc:
  Fixed bug that caused archive.test to fail with: Warning: Found locks from different threads for lock 't2' in 'write' at 'start of release lock'...
  The reason was that the TL_WRITE_DELAYED lock was changed to TL_WRITE_ALLOW_WRITE which conflicted with how the lock was used in sql_insert.cc (in particular with thr_upgrade_write_delay_lock())
