dm clone: replace spin_lock_irqsave with spin_lock_irq
[ Upstream commit 6ca43ed8376a51afec790dd484a51804ade4352a ]
If we are in a place where it is known that interrupts are enabled,
functions spin_lock_irq/spin_unlock_irq should be used instead of
spin_lock_irqsave/spin_unlock_irqrestore.
spin_lock_irq and spin_unlock_irq are faster because they don't need to
push and pop the flags register.
