description:
Fix ptyfs link and symlink ops.

They were set (via macro obfuscation just eliminated) to
genfs_abortop, which is the wrong thing. These code paths are
currently inaccessible because of EROFS enforcement in namei, but if
either were reached odd behavior would likely ensue. Use
genfs_eopnotsupp like the rest of the ops that don't make sense here.
