Dave Anderson eb2e5f452a hfs: fix memory leak when unmounting
When an HFS filesystem is unmounted, it leaks a 2-page bitmap.  Also,
under extreme memory pressure, it's possible that hfs_releasepage() may
use a tree pointer that has not been initialized, and if so, the release
request should just be rejected.

[akpm@linux-foundation.org: free_pages(0) is legal, remove obvious comment]
