barrier: replace boolean-switch statement with if/else

Squash some ugly warnings, and make the code a little bit simpler by
removing some unneeded goto jumps.

On Ubuntu 16.04 the following warnings were reported by Amudhan:

      CC	   barrier.lo
    barrier.c: In function ‘notify’:
    barrier.c:499:33: warning: switch condition has boolean value [-Wswitch-bool]
                             switch (past) {
                                     ^
    barrier.c: In function ‘reconfigure’:
    barrier.c:565:25: warning: switch condition has boolean value [-Wswitch-bool]
                     switch (past) {
                             ^
