btrfs: Remove unused locking functions

Browse Source 
Those were split out of btrfs_clear_lock_blocking_rw by
aa12c02778 ("btrfs: split btrfs_clear_lock_blocking_rw to read and write helpers")
however at that time this function was unused due to commit
5239834016 ("Btrfs: kill btrfs_clear_path_blocking"). Put the final
nail in the coffin of those 2 functions.
