[PATCH] chan.c: fix chan.c to return channel number when in monitor mode and on a fixed channel.

[Nicholas Hockey <nhockey@xxxxxxxxx>]

(sorry if this is not right, its been nearly 10 years since i
submitted a kernel patch)

Fixes: When monitoring a fixed channel, chan.c does not report what
channel it is on.
