Gnumach cleanup 5 - Control reaches end of non-void function

[Barry deFreese]

Heya gents,

Just a quick one to clean the remaining warnings in the title.

I realize that this reverts a couple of the things I sent on my last
patch but several of the lpr functions really return nothing so should
have been void in the first place.

Thanks as always,

Barry deFreese (aka bddebian)
