Fix bug 1076215 (Unnecessary AHI scan in
buf_LRU_mark_space_was_deleted).

This bug is our version of upstream bug
http://bugs.mysql.com/bug.php?id=64284: there is no need to scan
buffer pool for AHI entries after the B-trees for the tablespace have
been dropped, as that will already clean them.

Fixed by removing the AHI scan in buf_LRU_mark_space_was_deleted().
For debug builds, following Facebook patch changes, attempt the AHI
scan and assert that it removed zero entries. For this, patch
buf_LRU_drop_page_hash_for_tablespace() to return the number of AHI
entries found.
