    LINUX: Reduce stack depth on recursive symlink res
    
    Instead of calling vfs_follow_link inside afs_linux_follow_link
    ourselves, we can just resolve the next step of the symlink resolution
    and set the result in nd_set_link(), freeing the string in
    .put_link().
    
    For kernels without a usable symlink text cache, this reduces call
    depth when resolving a path containing many symlinks by two frames per
    layer of indirection, allowing for more deeply-nested symlink paths to
    be usable.
