Subject: [PATCH 03/19] KVM: x86/mmu: Remove unused "vcpu" of reset_{tdp,ept}_shadow_zero_bits_mask()

From: Jinrong Liang <cloudliang@...cent.com>

The "struct kvm_vcpu *vcpu" parameter of reset_ept_shadow_zero_bits_mask()
and reset_tdp_shadow_zero_bits_mask() is not used, so remove it.

No functional change intended.
