All existing DECLARE_TASKLET() users had a "0" data argument, it has been removed here as well.

This is due to: 10760dde9be3 ("MIPS: Remove support for LASAT") preceeding b13fecb1c3a6 ("treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()") upstream and the former not being present in 5.4.y. Fix this by changing DECLARE_TASKLET to DECLARE_TASKLET_OLD in arch/mips/lasat/pcivue_proc.c.
