md: raid0: fix error return from create_stripe_zones.
commit 58ebb34c49fcfcaa029e4b1c1453d92583900f9a upstream.
Create_stripe_zones returns an error slightly differently to
raid0_run and to raid0_takeover_*.
The error returned used by the second was wrong and an error would
result in mddev->private being set to NULL and sooner or later a
crash.
So never return NULL, return ERR_PTR(err), not NULL from
create_stripe_zones.
This bug has been present since 2.6.35 so the fix is suitable
for any kernel since then.
