drm/i915/display: Fix warning callstack for imbalance wakeref
While executing i915_selftest, wakeref imbalance warning is seen
with i915_selftest failure.
Currently when Driver is suspended, while doing unregister
it is taking wakeref without resuming the device.
This patch is resuming the device, if driver is already suspended
and doing unregister process.
