Adrian Chadd 656380e725 Wrap the rate control re-init code in a lock, to serialise it with
concurrent updates from any completing transmits in other threads.

This was exposed when doing power save work - net80211 is constantly
doing reassociations and it's causing the rate control state to get
blanked out.  This could cause the rate control code to assert.

This should be MFCed to stable/10 as it's a stability fix.

Tested:

* AR5416, STA

MFC after:	7 days
