Tsukasa OI Sept. 25, 2022, 8:42 a.m. UTC 
  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.

sim/ChangeLog:

	* common/genmloop.sh: Initialize pbb_br_type and pbb_br_npc
	by default.
