wifi: ath9k_htc: Abort software beacon handling if disabled
A malicious USB device can send a WMI_SWBA_EVENTID event from an
ath9k_htc-managed device before beaconing has been enabled. This causes
a device-by-zero error in the driver, leading to either a crash or an
out of bounds read.
Prevent this by aborting the handling in ath9k_htc_swba() if beacons are
not enabled.
