ocfs2/cluster: replace the interrupt safe spinlocks with common ones
There actually no hardware or software interrupts in the context which
using o2hb_live_lock, so we don't need to worry about race conditions
caused by irq/softirq with spinlock held. Turning off irq is not good
for system performance after all. Just replace them with a non
interrupt safe function.
