KVM: MMU: Drop unused return value of kvm_mmu_remove_some_alloc_mmu_pages
freed_pages is never evaluated, so remove it as well as the return code kvm_mmu_remove_some_alloc_mmu_pages so far delivered to its only user. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
