barrier: initalize file descriptors with -1

Explicitly initalize descriptors using explicit assignment like
bus_error. This makes barriers follow the same conventions as
everything else and makes things a bit simpler too.

Rename barier_init to barier_create so it is obvious that it is
not about initialization.

Remove some parens, etc.
