kvm: x86: Check memopp before dereference (CVE-2016-8630)
Commit 41061cdb98 ("KVM: emulate: do not initialize memopp") removes a
check for non-NULL under incorrect assumptions. An undefined instruction
with a ModR/M byte with Mod=0 and R/M-5 (e.g. 0xc7 0x15) will attempt
to dereference a null pointer here.
Fixes: 41061cdb98a0bec464278b4db8e894a3121671f5
