Johannes Berg 0b1621f623 mac80211: fix crash if bitrate calculation goes wrong ...

commit d86aa4f8ca upstream.

If a frame's timestamp is calculated, and the bitrate
calculation goes wrong and returns zero, the system
will attempt to divide by zero and crash. Catch this
case and print the rate information that the driver
reported when this happens.
