Chris Mason d5550c6315 Btrfs: don't lock bits in the extent tree during writepage ...

At writepage time, we have the page locked and we have the
extent_map entry for this extent pinned in the extent_map tree.
So, the page can't go away and its mapping can't change.

There is no need for the extra extent_state lock bits during writepage.
