Subject: [PATCH] kvm:powerpc:Fix return statements for wrapper functions in the file book3s_64_mmu_hv.c

From: Nicholas Krause <[email-masked]>
Date: Mon, 10 Aug 2015 11:27:31 -0400

This fixes the wrapper functions kvm_umap_hva_hv and the function
kvm_unmap_hav_range_hv to return the return value of the function
kvm_handle_hva or kvm_handle_hva_range that they are wrapped to
call internally rather then always making the caller of these
wrapper functions think they always run successfully by returning
the value of zero directly.
