[PATCH 1/2] net: atm: pppoatm: use tasklet_init to initialize wakeup tasklet

[Emil Renner Berthing <kernel@esmil.dk>]

Previously a temporary tasklet structure was initialized on the stack
using DECLARE_TASKLET_OLD() and then copied over and modified. Nothing
else in the kernel seems to use this pattern, so let's just call
tasklet_init() like everyone else.
