afs.c: Rename ->handler of struct callback_query to ->cb.

The term "handler" is already overloaded. Besides command and signal
handlers we have callback result handlers, table event handlers and
max size handlers for para buffers. The simple "cb" is a shorter and
clearer name for the callback function pointer.
