[PATCH] KVM: arm64: fix boolreturn.cocci warnings

[kernel test robot]

From: kernel test robot <l...@intel.com>

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.
