Description: Fix-up sleeping in sound/pci. These changes fall under the
following two categories:

        1) Replace schedule_timeout() with msleep() to guarantee the
        task delays as expected. This also involved replacing/removing
        custom sleep functions.
        2) Do not assume jiffies will only increment by one if you
        request a 1 jiffy sleep, i.e. use time_after/time_before in
        while loops.
