[PATCH x86/core/percpu 1/2] x86, percpu: fix minor bugs in setup_percpu.c

[Tejun Heo <tj@kernel.org>]

Recent changes in setup_percpu.c made a now meaningless DBG()
statement fail to compile and introduced a
comparison-of-different-types warning.  Fix them.

Compile failure is reported by Ingo Molnar.
