drm/i915/psr: Do not unnecessarily remove underrun on idle PSR WA

Browse source

We are currently removing underrun on idle PSR WA even if it's not
applied. Fix this by checking pkg_c_latency_used on PSR exit as well.

Fixes: 9b1795e9b0 ("drm/i915/psr: Underrun on idle PSR wa only when pkgc latency > delayed vblank")
