Currently we are printing one igt_warn for each CRC mismatch, which gets
quite overwhelming with having to see the same error 8 times for each
color tested:

WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3
WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3
WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3
WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3
WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3
WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3
WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3
WARNING: CRC mismatch with format NV12 (0x3231564e) on A.3

Since the most interesting information here is which format on which
pipe/plane is broken we can skip igt_warn just once.

For those weirder and rarer case where just certain colors would fail we
still provide the count and the mask of color array indices that failed:

WARNING: CRC mismatches with format NV12 (0x3231564e) on A.3 with 8/8 solid colors tested (0xFF)

v2 (Petri): Print a mask so it's possible to know which colors failed.
