drm/i915: don't disable/reenable IVB error interrupts when not needed

Browse source

If the error interrupts are already disabled, don't disable and
reenable them. This is going to be needed when we're in PC8+, where
all the interrupts are disabled so we won't risk re-enabling
DE_ERR_INT_IVB.

v2: Use dev_priv->irq_mask (Chris)
