[PATCH] drm/i915: vlv: fix RPS interrupt mask setting

[Imre Deak <imre.deak@intel.com>]

This typo may lead to missed RPS interrupts and as a result a too
low or too high frequency for the current workload. The interrupt mask
will be set properly at a subsequent GPU idle event, but can get
corrupted again at the next RPS up/down event.
