btrfs: remove stale comment about locking at btrfs_search_slot()
The comment refers to the old extent buffer locking code, where we used to have custom locks that had blocking and spinning behaviour modes. That is not the case anymore, since we have transitioned to rw semaphores, so the comment does not offer any value anymore. Remove it.
