[PATCH] Deleted no longer used 'if' clauses (ALG) from firewall init

[Matthias Fischer <matthias.fischer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 3096 bytes --]

In https://git.ipfire.org/?p=ipfire-2.x.git;a=commit;h=ffafaa71a6970a8c3d0942247feb37facfe24d25
all ALGs were removed from UI.

But they remained - somehow - in the initscript (firewall).

I tried to remove the remnants - hopefully in the correct way.
