lib/igt_kms: Add fail exit branch in do_display_commit()

Browse Source 
On Cherryview PIPE_C can only be connected to PORT_D (bspec).
The driver properly reports the crtc_mask for the encoder, however the
mismatch between pipe and port is not reported back to the test.

Add support for detecting this case so the test can be skipped.

v2: Apply review comments (Marius)
