KVM: s390: cpu model: use proper define for facility mask size

We're using S390_ARCH_FAC_LIST_SIZE_U64 instead of 
S390_ARCH_FAC_MASK_SIZE_U64 to define the array size of the facility 
mask. Let's properly use S390_ARCH_FAC_MASK_SIZE_U64. Note that both
values are the same and, therefore, this is a pure cleanup.
"

I'm not convinced there is a bug and that this deserves a "Fixes:".
