[PATCH 13/15] KVM: X86: Remove useless code to set role.gpte_is_8_bytes when role.direct

role.gpte_is_8_bytes is unused when role.direct, so this code is
useless so far.

And role.gpte_is_8_bytes is going to be used for indicating if gpte is 4
bytes even when role.direct is true when shadowpaging, so this code
has to be removed for preparation.
