Subject: ath11k: qmi: avoid error messages when dma allocation fails
From: Aaron Ma <aaron.ma@xxxxxxxxxxxxx>
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.
