[Mesa-dev] [PATCH v4] anv: handle failures when growing reloc lists

Growing the reloc list happens through calling anv_reloc_list_add() or
anv_reloc_list_append(). Make sure that we call these through helpers
that check the result and set the batch error status if needed.
v2:
- Handling the crashes is not good enough, we need to keep track of
the error, for that, keep track of the errors in the batch instead (Jason).
- Make reloc list growth go through helpers so we can have a central
place where we can do error tracking (Jason).
v3:
- Callers that need the offset returned by anv_reloc_list_add() can
compute it themselves since it is extracted from the inputs to the
function, so change the function to return a VkResult, make
anv_batch_emit_reloc() also return a VkResult and let their callers
do the error management (Topi)
v4:
- Let anv_batch_emit_reloc() return an uint64_t as it originally did,
there is no real benefit in having it return a VkResult.
- Do not add an is_aux parameter to add_surface_state_reloc(), instead
do error checking for aux in add_image_view_relocs() separately.
