drm/i915/dp_link_training: Check for pending autoretrain explicitly

Browse Source 
Check explicitly for a pending autoretrain by matching
seq_train_failures == 1.

This makes the actual condition clear, since at the point where the
counter is checked it is also below MAX_SEQ_TRAIN_FAILURES.

This also prepares for replacing the counter with an enum in a follow-up
change.
