(isc_destroy): Use scb->handlers->current instead of scb->fun.

	"current" of IscHandlerList objects points to the IscHandler
	object where the callbacks that should be used exist.  Once
	that changes was done, there is no need for the "scb->fun"
	member, so it was removed.

	IscHandlerList changes.
(ISC_SCALLFUN2): Analogous.
(ISC_SCALLFUN3): Analogous.

(ISC_HCALLFUN1): Adapted to IscHandlerList changes.
