drm/tilcdc: Fix irq free on unload

The driver only frees the reserved irq if priv->irq_enabled is set to
true. However, the driver mistakenly sets priv->irq_enabled to false,
instead of true, in tilcdc_irq_install(), and thus the driver never
frees the irq, causing issues on loading the driver a second time.
