Remove Linux crash lines (#64, #114)

[ziggi]

Fix for #64, #114.

Just removed two lines that give a crash. I've tested this very much and it pretty stable.

Why it stable? Because in latest Pawn these lines also does not exist: sc3.c#L2331-L2333. And I think it's a good reason to remove this.

Doesn't this remove tag checking for forwarded functions, or functions used before they are declared?

The latest PAWN compiler is almost a completely different language. I wouldn't trust that as an example of what can be changed. There's also no guarantee that they haven't just been moved or implemented differently. I'm with Oscar - do you know what they were there for, removing lines does imply removing functionality and they clearly do something with tags.

The problem is not that line. The problem is that arg[argidx].tags has an invalid value. When I inspected it in gdb, I saw 0x4 - and it's a pointer!

Something has gone wrong before it reached this line.

I changed the above if-statement to this: https://github.com/compuphase/pawn/blob/6d82fa4bfa3df019f8144dcb75b994240f8b9a7e/compiler/sc3.c#L2236

It fixes the segfault.

Seems to it really works, thanks!
