  Fixed valgrind warning.
storage/maria/ma_bitmap.c:
  Fixed wrong call parameter to pagecache_unlock_by_link() that caused assert crash in pagecache
storage/maria/ma_pagecache.c:
  Fixed possible error in pagecache_wait_lock() when hash_link was not set. (We never hit this issue, but could be possible when two threads updates the same page.
