md/raid5: new alloc_stripe() to allocate an initialize a stripe.

Browse source

The new batch_lock and batch_list fields are being initialized in
grow_one_stripe() but not in resize_stripes().  This causes a crash
on resize.

So separate the core initialization into a new function and call it
from both allocation sites.
