[PATCH] fcntl(F_SETSIG) fix
fcntl(F_SETSIG) no longer works on leases because
lease_release_private_callback() gets called as the lease is copied in
order to initialise it.
The problem is that lease_alloc() performs an unnecessary initialisation,
which sets the lease_manager_ops. Avoid the problem by allocating the
target lease structure using locks_alloc_lock().
