Log Message:
Pull up following revision(s) (requested by hannken in ticket #1477):
        sys/kern/vfs_wapbl.c: revision 1.38
Wapbl_register_deallocation(): the taken reader lock is not sufficient to
protect wl_dealloc* members.  Take the mutex here and change the lock
requirements of these fields to "writer lock or mutex".
This error lead to file system corruption and "freeing free block" panics.
