disp: msm: dp: check for aux abort in sim mode

Browse Source 
In sim mode, the dp driver is not checking for the aux state before
processing an aux request. This ends up causing the drm framework to
unnecessarily wait for 4 seconds while destroying a stream.

This change adds the check for aux state to align with the behavior
of a real sink.
