md/raid1: perform mem allocation before disabling writes during resync.
Though this mem alloc is GFP_NOIO an so will not deadlock, it seems
better to do the allocation before 'raise_barrier' which stops any IO
requests while the resync proceeds.
raid10 always uses this order, so it is at least consistent to do the
same in raid1.
