mm/compaction: reverse the change that forbade sync migraton with __GFP_NO_KSWAPD
It's uncertain this has been beneficial, so it's safer to undo it. All other compaction users would still go in synchronous mode if a first attempt at async compaction failed. Hopefully we don't need to force special behavior for THP (which is the only __GFP_NO_KSWAPD user so far and it's the easier to exercise and to be noticeable). This also make __GFP_NO_KSWAPD return to its original strict semantics specific to bypass kswapd, as THP allocations have khugepaged for the async THP allocations/compactions.
