Subject: [patch 09/14] net: sundance: Use tasklet_disable_in_atomic().

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

tasklet_disable() is used in the timer callback. This might be distangled,
but without access to the hardware that's a bit risky.

Replace it with tasklet_disable_in_atomic() so tasklet_disable() can be
changed to a sleep wait once all remaining atomic users are converted.
