ath10k: high latency fixes for beacon buffer

Browse source 
[ Upstream commit e263bdab9c ]

Beacon buffer for high latency devices does not use DMA. other similar
buffer allocation methods in the driver have already been modified for
high latency path. Fix the beacon buffer allocation left out in the
earlier high latency changes.
