[PATCH] ath9k/ath10k: remove unnecessary channel_switch_beacon callbacks

[Luca Coelho]

From: Luciano Coelho <luciano.coelho at intel.com>

The channel_switch_beacon callback is optional, so it doesn't have to
be defined if it's not going to do anything useful with it.  Both
ath9k and ath10k define the callback and just returns.  This commit
removes them.

I'm plannnig to remove the channel_switch_beacon callback (actually,
replace it with a more generic one that can be used for STA and other
iftypes too) and ath9k/ath10k are the only (non) users of it. ;)
