We previously returned -EPERM but it can be returned for various other reasons too. Let's use -ENOLINK instead as this value shouldn't be used currently. This allows users of CHASE_SAFE to detect without any ambiguities when unsafe transitions are encountered by chase_symlinks(). All current users of CHASE_SAFE that explicitly reacted on -EPERM have been converted to react on -ENOLINK.
