[PATCH v2] KVM: x86: Assign correct value to array.maxnent

[Xiaoyao Li]

Delay the assignment of array.maxnent to use correct value for the case
cpuid->nent > KVM_MAX_CPUID_ENTRIES.

Fixes: e53c95e8d41e ("KVM: x86: Encapsulate CPUID entries and metadata in struct")
Signed-off-by: Xiaoyao Li <xiaoyao.li@xxxxxxxxx>

v2:
   - remove "const" of maxnent to fix build error.
