[PATCH] wifi: ath12k: remove memset with byte count of 278528

[Kalle Valo]

From: Kalle Valo <quic_kvalo at quicinc.com>

Sparse warns:

drivers/net/wireless/ath/ath12k/dp.c:1471:15: warning: memset with byte count of 278528

There's no need to use memset() here, instead call dma_alloc_coherent() with __GFP_ZERO.

While at it, remove an extra line before the error handler.
