percpu: fix spurious alignment WARN in legacy SMP percpu allocator
Impact: remove spurious WARN on legacy SMP percpu allocator Commit f2a8205c4ef1af917d175c36a4097ae5587791c8 incorrectly added too tight WARN_ON_ONCE() on alignments for UP and legacy SMP percpu allocator. Commit e317603694bfd17b28a40de9d65e1a4ec12f816e fixed it for UP but legacy SMP allocator was forgotten. Fix it. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Sachin P.
