KVM: x86: Don't re-execute instruction when not passing CR2 value
[ Upstream commit 9b8ae63798cb97e785a667ff27e43fa6220cb734 ]
In case of instruction-decode failure or emulation failure,
x86_emulate_instruction() will call reexecute_instruction() which will
attempt to use the cr2 value passed to x86_emulate_instruction().
However, when x86_emulate_instruction() is called from
emulate_instruction(), cr2 is not passed (passed as 0) and therefore
it doesn't make sense to execute reexecute_instruction() logic at all.
Fixes: 51d8b66199e9 ("KVM: cleanup emulate_instruction")
