[PATCH] 8139too: remove interruptible_sleep_on_timeout() usage

From: Nishanth Aravamudan <nacc@us.ibm.com>

One thing I would have preferred using here is use wait_event*(), but
there is no condition. However, try_to_freeze(PF_FREEZE) could be used
as one, if the return condition matters -- it can return 0 or 1, from
what I understand. If the intent is to loop until the task is "frozen",
then I can revise the patch to use wait_event_interruptible_timeout().

Replace deprecated interruptible_sleep_on_timeout() function calls
with direct wait-queue usage. I did not find direct
wake_up_interruptible() function call in this file for the wait-queue,
but that may not be an issue.

Patch is compile-tested.
