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.
