[PATCH] VFS: Fix memory leak with file leases

 The patch
 http://linux.bkbits.net:8080/linux-2.6/diffs/fs/locks.c@1.70??nav=index.html
 introduced a pretty nasty memory leak in the lease code. When freeing
 the lease, the code in locks_delete_lock() will correctly clean up
 the fasync queue, but when we return to fcntl_setlease(), the freed
 fasync entry will be reinstated.

 This patch ensures that we skip the call to fasync_helper() when we're
 freeing up the lease.
