[Mesa-dev] [PATCH] radv: increase aligment when allocating descriptors for meta operations

[Samuel Pitoiset]

We usually align to 0x100 when allocating descriptors and
resources in the upload BO. I assume some data were corrupted
because the alignment was too small. Be consistent (and safe)
and align internal descriptors to 0x100 as well.

This fixes a GPU hang at startup with X4 Foundations.
