NeilBrown b0c783b323 md/raid5: more incorrect BUG_ON in handle_stripe_fill. 
It is not incorrect to call handle_stripe_fill() when
a batch of full-stripe writes is active.
It is, however, a BUG if fetch_block() then decides
it needs to actually fetch anything.

So move the 'BUG_ON' to where it belongs.
