[igt-dev] [PATCH i-g-t] tests/kms_big_fb: Use igt_pipe_crc_get_current instead of igt_pipe_crc_collect_crc

[Vidya Srinivas]

CRC mismatch is seen between big and small CRC on
Gen11 systems for subtest y-tiled-32bpp-rotate-0.
Patch changes igt_pipe_crc_collect_crc to igt_pipe_crc_get_current
for collecting CRC for big and small fb to compare.
