[patch 5/9] block/pf: replace pf_sleep() with msleep_interruptible()

[janitor@sternwelten.at]

Any comments would be appreciated. This is a re-push of a patch I
submitted 20 July which hasn't been merged as of
2.6.9-rc1-mm5/2.6.9-rc2. 

Description: msleep_interruptible() is used instead of pf_sleep()
to guarantee the task delays as expected. The defintion of pf_sleep()
is also removed.
