[PATCH v3 02/10] KVM: x86: Capture "struct x86_exception" in inject_emulated_exception()

[Sean Christopherson]

From: Hou Wenlong <houwenlong.hwl@xxxxxxxxxxxx>

As all callers in inject_emulated_exception() use "struct x86_exception"
directly, capture it locally instead of using the context.

No functional change intended.
