percpu: fix locking regression in the failure path of pcpu_alloc()
While updating locking, b38d08f3181c ("percpu: restructure locking") broke pcpu_create_chunk() creation path in pcpu_alloc(). It returns without releasing pcpu_alloc_mutex. Fix it. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Julia Lawall <julia.lawall@lip6.fr>
