percpu: fix spurious alignment WARN in legacy SMP percpu allocator

Impact: remove spurious WARN on legacy SMP percpu allocator

Commit f2a8205c4e incorrectly added too
tight WARN_ON_ONCE() on alignments for UP and legacy SMP percpu
allocator.  Commit e317603694 fixed it
for UP but legacy SMP allocator was forgotten.  Fix it.
