hid: cp2112: Fix duplicate workqueue initialization

In the Linux kernel, the following vulnerability has been resolved:

hid: cp2112: Fix duplicate workqueue initialization

Previously the cp2112 driver called INIT_DELAYED_WORK within

cp2112_gpio_irq_startup, resulting in duplicate initilizations of the

workqueue on subsequent IRQ startups following an initial request. This

resulted in a warning in set_work_data in workqueue.c, as well as a rare

NULL dereference within process_one_work in workqueue.c.

Initialize the workqueue within _probe instead.
