Subject: [PATCH] KVM: PPC: remove unused varible

From: Alex Shi <alexs@...nel.org>

During build testing, we found a error:
/arch/powerpc/kvm/book3s_hv.c:4052:17: error: variable 'loops' set but not used [-Werror,-Wunused-but-set-variable]
                unsigned long loops = 0;
1 error generated.

Remove the unused variable could fix this.
