When CONFIG_SMP is not set, wbinvd_on_all_cpus() is not declared,
due to missing <asm/smp.h>.
Fixes this build error:
../drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c: In function
'i915_gem_object_get_pages_dmabuf':
../drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c:251:3: error: implicit
declaration of function 'wbinvd_on_all_cpus'; did you mean 'wrmsr_on_cpus'?
[-Werror=implicit-function-declaration]
wbinvd_on_all_cpus();
Fixes: a035154da45d ("drm/i915/dmabuf: add paranoid flush-on-acquire")
