drm/i915: Fix assert_plane warning during FDI link train 

assert_plane_enabled() is now triggering during FDI link train because
we no longer enable planes that early.

This problem got introduced in:
 commit a5c4d7bc18
 Author: Ville Syrjälä <ville.syrjala@linux.intel.com>

    drm/i915: Disable/enable planes as the first/last thing during modeset on ILK+

Just drop the assert since we shouldn't need planes for link training.

[danvet: Squash in fixup for now unused plane local variable, reported
by 0-day tester.]
