percpu: merge VERIFY_PERCPU_PTR() into its only user

Merge VERIFY_PERCPU_PTR() into non-CONFIG_SMP per_cpu_ptr() to make macro
similar to CONFIG_SMP per_cpu_ptr().  This will allow a follow-up patch to
refactor common code to a macro.

No functional changes, non-CONFIG_SMP per_cpu_ptr() was the only user of
VERIFY_PERCPU_PTR().
