at86rf230.c and derivatives avoid this problem by setting
phy->current_* in the *_channel function.

But I'd agree that it's nicer to do this in one place, not in
every driver.

In case a driver had a weird failure mode in which it leaves the
original channel but only makes it halfway to the new channel, it
could still set phy->current_* and return an error. So there's no
loss of functionality with your change.
