Hi Jens,

Here you have a second round of fixes for pblk. They are in essence bug
fixes including a double-free reported by Dan.

There is also regression fix for pblk removal, which was introduced with
the new metadata scheduler. This fix makes that removing a pblk instance
takes again at most 2 seconds.

Finally, I also included a patch for double checking the L2P to verify a
cache hit before reading from the write cache. We have experienced a
database not issuing fsync before reading recently written metadata
triggering a bad cache read. We verified it this week. This patch is an
easy fix that we can make in pblk.

Applied for 4.13, thanks.
