Previously, bitrate showed uninitialized buffer when no rate info

When would this happen?
I could see in mesh STA connection with 11n and legacy mixed.
STA A has disable_ht=1.
STA B has disable_ht=0.

I recognized there was a issue on such a case. I will send a patch to
wpa_supplicant. Anyway, showing string message is better than showing
raw binary data.
How about we just add "(unknown)" or so and not return here?
Yes. First time, I supposed to use "unknown". But in the function
parse_bitrate(), nla_parse_nested() returns message "failed to parse
nested rate attributes!". This explains why the bitrate is unknown. So I
used explaining message. We could see the message like this.
tx bitrate: No rate info found!
rx bitrate: 48.0 MBit/s
