jump_label: Allow asm/jump_label.h to be included in assembly
commit 55dd0df781e58ec23d218376ea4a676e7362a98c upstream. Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__. Since these are kernel only headers, we don't need #ifdef __KERNEL__ so can simplify things a bit. If an architecture wants to use jump labels in assembly, it will still need to define a macro to create the __jump_table entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h for an example).
