[PATCH] KVM: x86: remove data variable from kvm_get_msr_common

[PATCH] KVM: x86: remove data variable from kvm_get_msr_common

[Nicolas Iooss]

Commit 609e36d372ad ("KVM: x86: pass host_initiated to functions that
read MSRs") modified kvm_get_msr_common function to use msr_info->data
instead of data but missed one occurrence.  Replace it and remove the
unused local variable.

Fixes: 609e36d372ad ("KVM: x86: pass host_initiated to functions that
read MSRs")
