KVM: arm64: Fix boolreturn.cocci warnings
arch/arm64/kvm/mmu.c:1114:9-10: WARNING: return of 0/1 in function 'kvm_age_gfn' with return type bool
arch/arm64/kvm/mmu.c:1084:9-10: WARNING: return of 0/1 in function 'kvm_set_spte_gfn' with return type bool
arch/arm64/kvm/mmu.c:1127:9-10: WARNING: return of 0/1 in function 'kvm_test_age_gfn' with return type bool
arch/arm64/kvm/mmu.c:1070:9-10: WARNING: return of 0/1 in function 'kvm_unmap_gfn_range' with return type bool
Return statements in functions returning bool should use
true/false instead of 1/0.
