Protect access to fore200e->available_cell_rate with rate_mtx lock to prevent potential data race.

The field fore200e.available_cell_rate is generally protected by the lock fore200e.rate_mtx when accessed. In all other read and write cases, this field is consistently protected by the lock, except for this case and during initialization.

That's not sufficient in terms of analysis.

You need to be able to articulate what can go wrong.
