Strange behavior with cl_maxdecals

[Nash]

You will need the attached file to reproduce this

1) Be sure your cl_maxdecals is at some non-0 value.
2) Shoot the green door in front of you with any hitscan weapon (pistol is fine) a few times (1 shot isn't enough)
3) Shoot the brown walls. Decals will appear as normal.
4) Type cl_maxdecals 0

The wall decals will not disappear. This ONLY happens when you shot the green (model-based) doors first. If you DON'T shoot the doors, cl_maxdecals will behave normally.

[_mental_]

Here is potential solution for this. However, I'm not 100% sure that we don't need to keep these invisible decals. Probably, we should take them into account instead, like "true" decals.
