staging: most: hdm-usb: Remove invalid reference error
commit e3479f77("staging: most: hdm-usb: Remove create_workqueue()") cancel_work_sync(&anchor->clear_work_obj) is introduced after freeing `anchor` causing a invalid reference error. This patch removes this error by shifting the call to cancel_work_sync before freeing `anchor`.
