[Intel-gfx] [PATCH v2 1/3] drm/i915: Reuse the aux_domain cached

[José Roberto de Souza]

intel_dp_detect() caches the aux_domain in the beginning of the
function as it is used twice, so lets also use it as the aux_domain
don't change in runtime by jumping to the end of function when
retrain the link fails.

v2: jumping to the end of the function instead of just reuse
aux_domain
