[src/trunk]: src/sys/dev/raidframe fix the function pointer and callback mess:
details: https://anonhg.NetBSD.org/src/rev/1398524143f8
branches: trunk
changeset: 464528:1398524143f8
user: christos <christos%NetBSD.org@localhost>

description:
fix the function pointer and callback mess:
- callback functions return 0 and their result is not checked; make them void.
- there are two types of callbacks and they used to overload their parameters
and the callback structure; separate them into "function" and "value"
callbacks.
- make the wait function signature consistent.
