[OpenAFS] Fileserver leaks Inode hash table entry after "rmdir"

[Rainer Toebbicke]

On rmdir, the fileserver checks that the directory is empty in 
DeleteTarget. Unfortunately it forgets to IH_RELEASE the directory 
handle afterwards, which ends up clobbering up the inode hash tables 
on fileserver doing lots of rmdirs (just for the anecdote we had hash 
buckets of 90 entries and others of > 150000...).

Obvious patch attached, Bcc'ed to openafs-bugs.
