HID: hid-steam: Fix issues with disabling both gamepad mode and lizard mode

Browse Source 
[ Upstream commit 05c4ede6951b5d8e083b6bb237950cac59bdeb92 ]

When lizard mode is disabled, there were two issues:

1. Switching between gamepad mode and desktop mode still functioned, even
though desktop mode did not. This lead to the ability to "break" gamepad mode
by holding down the Options key even while lizard mode is disabled

2. If you were in desktop mode when lizard mode is disabled, you would
immediately enter this faulty mode.

This patch properly disables the ability to switch between gamepad mode and the
faulty desktop mode by holding the Options key, as well as effectively removing
the faulty mode by bypassing the early returns if lizard mode is disabled.
