[PATCH] sunrpc: 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. The code, as is, is not wrong; however I see two
reasons to use msleep():
1) consistency across the kernel; and
2) milliseconds are far more human-comprehensible than jiffies.
