gpio: mpsse: fix reference leak in gpio_mpsse_probe() error paths

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

gpio: mpsse: fix reference leak in gpio_mpsse_probe() error paths

The reference obtained by calling usb_get_dev() is not released in the gpio_mpsse_probe() error paths. Fix that by using device managed helper functions. Also remove the usb_put_dev() call in the disconnect function since now it will be released automatically.
