Make walls_num a local variable

Make setup_level() and setup_level_bossrush() set the walls_num variable.
Make reset() accept the walls_num variable as an argument, to allow it
to create the correct number of walls. Finally remove the globl
WALLS_NUM variable and add the walls_num local variable to invader's and
bossrush's main().
