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

Browse source

[ Upstream commit 1e876e5a08 ]

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.
