When Wacom devices wake up from a sleep, the switch mode command
(wacom_query_tablet_data) is needed before wacom_open is called.
wacom_query_tablet_data should not be executed inside wacom_open
since wacom_open is called more than once during probe.

wacom_retrieve_hid_descriptor is removed from wacom_resume due
to the fact that the required descriptors are stored properly
upon system resume.
