[PATCH net] net: hdlc_x25: Return meaningful error code in x25_open

[Xie He]

It's not meaningful to pass on LAPB error codes to HDLC code or other
parts of the system, because they will not understand the error codes.

Instead, use system-wide recognizable error codes.

Fixes: f362e5fe0f1f ("wan/hdlc_x25: make lapb params configurable")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
