    fusefs: remove the obsolete rename_lock
    
    This lock was included in the original GSoC submission.  Its purpose
    seems to have been to prevent concurrent FUSE_RENAME operations for the
    current mountpoint, as well as to synchronize FUSE_RENAME with
    fuse_vnode_setparent.  But it's obsolete, now that ef6ea91593e added
    mnt_renamelock .
