Sean Christopherson fa079a0616 irqbypass: Drop pointless and misleading THIS_MODULE get/put ...

Drop irqbypass.ko's superfluous and misleading get/put calls on
THIS_MODULE.  A module taking a reference to itself is useless; no amount
of checks will prevent doom and destruction if the caller hasn't already
guaranteed the liveliness of the module (this goes for any module).  E.g.
if try_module_get() fails because irqbypass.ko is being unloaded, then the
kernel has already hit a use-after-free by virtue of executing code whose
lifecycle is tied to irqbypass.ko.
