btrfs: move extent locking outside of btrfs_truncate_inode_items
Currently we are locking the extent and dropping the extent cache for
any inodes we truncate, unless they're in the tree log. We call this
helper from:
- truncate
- evict
- tree log
- free space cache truncation
For evict we've already dropped all of the extent cache for this inode
once we've gotten here, and we're the only one accessing this inode, so
this step is unnecessary.
For the tree log code we already skip this part.
Pull this work into the truncate path and the free space cache
truncation path.
