[PATCH 004 of 4] md: Fix an occasional deadlock in raid5 - FIX

[NeilBrown <neilb@suse.de>]

(This should be merged with fix-occasional-deadlock-in-raid5.patch)

As we don't call stripe_handle in make_request any more, we need to
clear STRIPE_DELAYED to (previously done by stripe_handle) to ensure
that we test if the stripe still needs to be delayed or not.
