iris: Fix CCS check in iris_texture_subdata().
The intention here was to check "Would the GPU be able to compress
this if we used the PBO-based texture upload path?" Prior to Gen12,
that meant checking for CCS_E. On Gen12, there are a lot more types
of compression, and basic CCS_E was replaced by GEN12_CCS_E, making
this check simply not work, so we'd take the CPU path instead.
Instead, check if it has CCS, and isn't the basic "fast clear" CCS_D.
