dca: redesign locks to fix deadlocks
commit eb4400e3a040b90a3ad805b01fcbc99a5f615c8f upstream.
Change spin_locks to irqsave to prevent dead-locks.
Protect adding and deleting to/from dca_providers list.
Drop the lock during dca_sysfs_add_req() and dca_sysfs_remove_req() calls
as they might sleep (use GFP_KERNEL allocation).
