btrfs: rename __btrfs_tree_lock() and __btrfs_tree_read_lock()
Browse files Browse the repository at this point in the history 
The __btrfs_tree_lock() and __btrfs_tree_read_lock() are using a naming
with a double underscore prefix, which is specially not proper for
exported functions. Remove the double underscore prefix from their name
and add the "_nested" suffix.
