intel_th: Fix a deadlock in modprobing

commit a36aa80f3cb2540fb1dbad6240852de4365a2e82 upstream.

Driver initialization tries to request a hub (GTH) driver module from
its probe callback, resulting in a deadlock.

This patch solves the problem by adding a deferred work for requesting
the hub module.
