x86/kvm: Move l1tf setup function

Browse source

In preparation of allowing run time control for L1D flushing, move the
setup code to the module parameter handler.

In case of pre module init parsing, just store the value and let vmx_init()
do the actual setup after running kvm_init() so that enable_ept is having
the correct state.

During run-time invoke it directly from the parameter setter to prepare for
run-time control.
