PF_traceline: change Host_Error when a NaN is detected to a Con_Warning.

Browse source 
This only affects the case when the developer cvar is set, we already ignore NaN's here.

negke reports getting the nan error with this debug progs.dat: http://negke.fov120.com/files/progsbjp.zip (rename to pak0.pak + install as a mod)
and his sm133_neg!ke.bsp: https://www.quaddicted.com/reviews/sm133_pack.html (walk over the zombie to activate a lightning trap)
