Subject: [PATCH AUTOSEL 4.19 143/252] iommu/arm-smmu-v3: Populate VMID field for CMDQ_OP_TLBI_NH_VA

From: Shameer Kolothum <shameerali.kolothum.thodi@...wei.com>

[ Upstream commit 935d43ba272e0001f8ef446a3eff15d8175cb11b ]

CMDQ_OP_TLBI_NH_VA requires VMID and this was missing since
commit 1c27df1c0a82 ("iommu/arm-smmu: Use correct address mask
for CMD_TLBI_S2_IPA"). Add it back.

Fixes: 1c27df1c0a82 ("iommu/arm-smmu: Use correct address mask for CMD_TLBI_S2_IPA")
