KVM: Use vcpu-specific gva->hva translation when querying host page size
Use kvm_vcpu_gfn_to_hva() when retrieving the host page size so that the
correct set of memslots is used when handling x86 page faults in SMM.
Fixes: 54bf36aac520 ("KVM: x86: use vcpu-specific functions to read/write/translate GFNs")
