Do not try to return 0 from log_debug()

As @yuwata correctly points out, this became broken when log_debug()
started returning -EIO. I wanted to preserve this pattern, but it turns
out it is not very widely used, and preserving it would make the whole
thing, already quite complicated, even more complex.

log_debug() is made like log_info() and friends, and returns void.
