KVM: x86: Factor out x86 instruction emulation with decoding
[ Upstream commit 4aa2691dcbd38ce1c461188799d863398dd2865d ]
Move the instruction decode part out of x86_emulate_instruction() for it
to be used in other places. Also kvm_clear_exception_queue() is moved
inside the if-statement as it doesn't apply when KVM are coming back from
userspace.
