[PATCH net-next] net: dlink: fix several spelling mistakes in comments

[Yeounsu Moon <yyyynoom@gmail.com>]

This patch fixes multiple spelling mistakes in dl2k driver comments:

- "deivices" -> "devices"
- "Ttransmit" -> "Transmit"
- "catastronphic" -> "catastrophic"
- "Extened" -> "Extended"

Also fix incorrect unit description: `rx_timeout` uses 640ns increments,
not 64ns.
- "64ns" -> "640ns"

These are comment-only changes and do not affect runtime behavior.
