drm/i915: use drm_modeset_lock_assert_held() in intel_connector_get_pipe()

Browse Source 
In the intel_connector_get_pipe() function, we check if
connection_mutex is held and generate our own WARN_ON if that's the
case.  Instead of generating a non-standard warning for a mutex issue,
we should use the standard lockdep framework.

Change the function to use drm_modeset_lock_assert_held() instead.
