wifi: rtlwifi: usb: fix workqueue leak when probe fails

rtl_init_core creates a workqueue that is then assigned to rtl_wq.
rtl_deinit_core does not destroy it. It is left to rtl_usb_deinit, which
must be called in the probe error path.

Fixes: 2ca20f79e0d8 ("rtlwifi: Add usb driver")
Fixes: 851639fdaeac ("rtlwifi: Modify some USB de-initialize code.")
