[Intel-gfx] [PATCH i-g-t] test/kms_plane_lowres: Fix display_commit_mode() so it returns the crc

[Arkadiusz Hiler]

Compiler complained on crc_lowres and crc_hires2 being uninitialized
and indeed, display_commit_mode() seems to have intention of retruning
the value through the parameter that is only a single pointer.

This couses only the local copy of the pointer, the one inside
display_commit_mode(), to be overwritten.

Let's fix that!

Also add missing hires crc comparison (M. Kahola).
