[Tom: fix backport to 5.4.y]

AUTOSEL backport to 5.4.y of:
b13fecb1c3a6 ("treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()")
changed all locations of DECLARE_TASKLET with DECLARE_TASKLET_OLD,
except one, in arch/mips/lasat/pcivue_proc.c.

This is due to:

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.
