Meh, just omit the kerneldoc comment.

It's kinda silly, but I think it's worth landing this below gpa_to_gfn() so that
there's no need to open code the shift.
And I have a (very) slight preference for an early return.
static inline void kvm_gpc_mark_dirty_in_slot(struct gfn_to_pfn_cache *gpc)
{
lockdep_assert_held(&gpc->lock);
if (!gpc->memslot)
return;
mark_page_dirty_in_slot(gpc->kvm, gpc->memslot, gpa_to_gfn(gpc->gpa));
}
