[PATCH 1/3] HID: hid-lenovo-go-s: Fix signedness bug

[Ethan Tidmore]

The function get_endpoint_address() returns type u8 but in its error
path returns -ENODEV. Also, every variable that is assigned from this
function is type int.

Change return type to int from u8.

Detected by Smatch:
drivers/hid/hid-lenovo-go-s.c:391 get_endpoint_address() warn:
signedness bug returning '(-19)'
