[Intel-gfx] [PATCH i-g-t] tests/kms_plane_multiple: Fix reference CRC

[Mika Kahola]

When grabbing reference CRC with igt_pipe_crc_get_crcs() the number of
words in igt_crc_t structure was incorrectly collected. The fix here is
to switch to igt_pipe_crc_collect_crc() function when collecting CRC for
reference frame.

The problem was caught by CI system and at least affects on HSW platform.
