md/raid5: add missing spin_lock_init.
commit b17459c05000fdbe8d10946570a26510f86ec0f raid5: add a per-stripe lock added a spin_lock to the 'stripe_head' struct. Unfortunately there are two places where this struct is allocated but the spin lock was only initialised in one of them. So add the missing spin_lock_init. Signed-off-by: NeilBrown <neilb@suse.de>
