alloc_percpu: fix UP build

Impact: build fix

the !SMP branch had a 'gfp' leftover:

 include/linux/percpu.h: In function '__alloc_percpu':
 include/linux/percpu.h:160: error: 'gfp' undeclared (first use in this function)
 include/linux/percpu.h:160: error: (Each undeclared identifier is reported only once
 include/linux/percpu.h:160: error: for each function it appears in.)

Use GFP_KERNEL like the SMP version does.
