x86/mm/tlb: Unify flush_tlb_func_local() and flush_tlb_func_remote()
The unification of these two functions allows to use them in the updated SMP infrastrucutre. To do so, remove the reason argument from flush_tlb_func_local(), add a member to struct tlb_flush_info that says which CPU initiated the flush and act accordingly. Optimize the size of flush_tlb_info while we are at it. Unfortunately, this prevents us from using a constant tlb_flush_info for arch_tlbbatch_flush(), but in a later stage we may be able to inline tlb_flush_info into the IPI data, so it should not have an impact eventually.
