s390x/storage attributes: fix CMMA_BLOCK_SIZE usage
The macro CMMA_BLOCK_SIZE was defined but not used, and a hardcoded
value was instead used in the code.
This patch fixes the value of CMMA_BLOCK_SIZE and uses it in the
appropriate place in the code, and fixes another case of hardcoded
value in the KVM backend, replacing it with the more appropriate
constant KVM_S390_CMMA_SIZE_MAX.
