Subject: [PATCH 1/5] kvm/kvm_main: Modify the offset type to size_t, which is consistent with the calling function

The offset variable is called size_t in the calling function.
Considering the number of bits in different architectures (32 and 64
represent different types), change it to a consistent variable.
