Subject: cxgb4: zero the HMA memory
Patch-mainline: v4.17-rc5
Git-commit: 2b928749f9ba781085442d1f8832f057cbf458a1
References: bsc#1097585 bsc#1097586 bsc#1097587 bsc#1097588 bsc#1097583 bsc#1097584
firmware expects HMA memory to be zeroed, use __GFP_ZERO
for HMA memory allocation.
Fixes: 8b4e6b3ca2ed ("cxgb4: Add HMA support")
