    sim: Initialize pbb_br_* by default
    
    On the files generated by sim/common/genmloop.sh, variables pbb_br_type and
    pbb_br_npc are declared uninitialized and passed to other functions in some
    cases.  Despite that those are harmless, they will generate GCC warnings
    ("-Wmaybe-uninitialized").
    
    This commit ensures that pbb_br_type and pbb_br_npc variables are
    initialized to a harmless value.
