throttle_vm_writeout(): don't loop on GFP_NOFS and GFP_NOIO allocations
throttle_vm_writeout() is designed to wait for the dirty levels to subside.
But if the caller holds IO or FS locks, we might be holding up that writeout.
So change it to take a single nap to give other devices a chance to clean some
memory, then return.
