ppc: fix crash in ppc system single step support
There was a bogus case where two system debug ops get generated. This
patch removes the broken system debug op. This was a left over after
making some changes to correctly generate debug ops on branch
operations inside gen_goto_tb();
The test case against this patch is to turn on single stepping with
timers, boot a linux kernel, set a breakpoint a do_fork and in gdb
execute "si 3000". Then qemu-system-ppc will fault executing a debug
op, which should not have been executed.
