HID: mcp2221: fix report layout for gpio get

The documentation of the component (section 3.1.12 GET GPIO VALUES)
describes the hid report structure with two fields per gpio:
its value, followed by its direction.

However, the driver describes it with a wrong order:
direction followed by value.

Fix the structure representing the report answered by the chip to the
GET GPIO VALUES command.

Fixes commit 567b8e9fed8a ("HID: mcp2221: Fix GPIO output handling")
