Subject: [PATCH 5.15 727/846] ath11k: qmi: avoid error messages when dma allocation fails

From: Aaron Ma <aaron.ma@...onical.com>

commit b9b5948cdd7bc8d9fa31c78cbbb04382c815587f upstream.

qmi tries to allocate a large contiguous dma memory at first,
on the AMD Ryzen platform it fails, then retries with small slices.
So set flag GFP_NOWARN to avoid flooding dmesg.
