asahi: Always use resource size, not BO size

Browse source 
BOs can be oversized, as they can come from the BO cache. Make sure to
always use the resource layout size, not the BO size, when we need this
for some reason.

This fixes BO shadowing creating overlarge BOs, and also the attachment
size for submissions (probably doesn't matter, but it's more correct now).
