[net-next v2 6/8] net: sched: convert tasklets to use new tasklet_setup() API

[Allen Pais <allen.lkml@gmail.com>]

From: Allen Pais <apais@linux.microsoft.com>

In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
