[patch 14/26] net/slip: replace schedule_timeout() with msleep()

[domen@coderock.org]

Use msleep() instead of schedule_timeout() to guarantee
the task delays as expected. While the original code does use
TASK_INTERRUPTIBLE, it does not check for signals, so I believe msleep() is more
appropriate.
