axfer: return the number of file descriptors for I/O events from select(2) waiter

A call of select(2) returns error code at failure, the number of file
descriptors available I/O at success. Current implementation of
waiter abstraction for select(2) returns 0 at success and callers
can't get the number.

This commit fixes it.
