md: use stripe_head_state in ops_run_io()
From: Dan Williams <dan.j.williams@intel.com>
In handle_stripe after taking sh->lock we sample some bits into 's' (struct
stripe_head_state):
s.syncing = test_bit(STRIPE_SYNCING, &sh->state);
s.expanding = test_bit(STRIPE_EXPAND_SOURCE, &sh->state);
s.expanded = test_bit(STRIPE_EXPAND_READY, &sh->state);
Use these values from 's' in ops_run_io() rather than re-sampling the bits.
This ensures a consistent snapshot (as seen under sh->lock) is used.
