Subject: [PATCH linux-next] mips:mmu: fix boolreturn.cocci warnings

From: Jing Yangyang <jing.yangyang@....com.cn>

./arch/mips/kvm/mmu.c:489:9-10:WARNING: return of 0/1 in function
'kvm_test_age_gfn' with return type bool
./arch/mips/kvm/mmu.c:445:8-9  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.
