Regression in SpaceMousePro button mapping

[ideasman42]

In recent versions of SpaceNavD, SpaceMousePro's buttons are not working in Blender.

I bisected the error to: d537c9b.
Setting dev->bnhack = 0; resolves the issue in my case.

Patch:

I have a wired SpaceMousePro, starting sudo spacenavd -d shows the following output:

NOTE: if you wanted to test with Blender, use v4.3 as there is a bug in v4.4 which I was trying to fix when I noticed this issue.

Oh that's unfortunate... That commit was probably in response to a bug report, so I'll have to figure out what's going on. I'll ask you some followup questions once I've had a chance to look into it.
