KVM: VMX: Split out guts of EPT violation to common/exposed function

Browse source

[ Upstream commit c8563d1b69 ]

The difference of TDX EPT violation is how to retrieve information, GPA,
and exit qualification.  To share the code to handle EPT violation, split
out the guts of EPT violation handler so that VMX/TDX exit handler can call
it after retrieving GPA and exit qualification.
