Remove dead code in genautomata.c

[Bernd Schmidt]

In January 2006, Zack had a series of "chainsaw" patches for
genautomata. One of them left some dead code (a loop which used to count
states but is now useless), which the following patch removes.

Tested by verifying no warnings when compiling genautomata.c, and
identical insn-automata.c output for i686-linux and bfin-elf.  Ok?
