drm/i915/dp_link_training: Flush commits in debugfs entries

Browse source

Flush pending connector commits before accessing the link training state
from debugfs. Access to connector state - like the link training state -
that may be updated from an asynchronous commit tail must hold the
connection mutex and wait for the tail to complete. The commit tail
cannot hold the connection mutex, so all other accessors must wait for
it explicitly.
