HID: i2c-hid: fix size check and type usage
commit ac75a041048b8c1f7418e27621ca5efda8571043 upstream.
When convert char array with signed int, if the inbuf[x] is negative then
upper bits will be set to 1. Fix this by using u8 instead of char.
ret_size has to be at least 3, hid_input_report use it after minus 2 bytes.
