[PATCH] sonycd535: replace schedule_timeout() with msleep()

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

Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. Although TASK_INTERRUPTIBLE is used in the
original code, schedule_timeout() return conditions for such a state
are not checked appropriately; therefore, TASK_UNINTERRUPTIBLE should
be ok (and, hence, msleep()).
