asm-generic: percpu: Add assembly guard
Currently, asm/percpu.h is directly or indirectly included by
some assembly files on x86. Some of them (e.g., checksum_32.S)
are also used on um. But x86 and um provide different versions
of asm/percpu.h -- um uses asm-generic/percpu.h directly.
When SMP is enabled, asm-generic/percpu.h will introduce C code
that cannot be assembled. Since asm-generic/percpu.h currently
is not designed for use in assembly, and these assembly files
do not actually need asm/percpu.h on um, let's add the assembly
guard in asm-generic/percpu.h to fix this issue.
