Removed SPL_AC_3ARGS_INIT_WORK check

Browse Source 
All consumers of the kernel delayed work queues have been shifted
over to rely on the taskq implementation.  This compatibility code
can now be removed.  Any new callers which need this functionality
should use the taskq interfaces for delayed work items.
