Chris Mason dcbdd4dcb9 Btrfs: delete checksum items before marking blocks free 
Btrfs maintains a cache of blocks available for allocation in ram.  The
code that frees extents was marking the extents free and then deleting
the checksum items.

This meant it was possible the extent would be reallocated before the
checksum item was actually deleted, leading to races and other
problems as the checksums were updated for the newly allocated extent.

The fix is to delete the checksum before marking the extent free.
