dm integrity: fix to not disable/enable interrupts from interrupt context
Use spin_lock_irqsave and spin_unlock_irqrestore rather than
spin_{lock,unlock}_irq in submit_flush_bio().
Otherwise lockdep issues the following warning:
DEBUG_LOCKS_WARN_ON(current->hardirq_context)
WARNING: CPU: 1 PID: 0 at kernel/locking/lockdep.c:2748 trace_hardirqs_on_caller+0x107/0x180
