xfs: collapse xlog_state_set_callback in caller

The function is called from a single place, and it isn't just
setting the iclog state to XLOG_STATE_CALLBACK - it can mark iclogs
clean, which moves them to states after CALLBACK. Hence the function
is now badly named, and should just be folded into the caller where
the iclog completion logic makes a whole lot more sense.
