anv: check the return value of anv_execbuf_add_bo_bitset()

Because anv_execbuf_add_bo_bitset() calls anv_execbuf_add_bo(), which
can fail if its memory allocations fail.

I have seen dEQP tests exercising memory allocation failures during
anv_execbuf_add_bo(), but I don't think the path coming from
add_bo_biset() was specifically exercised. Anyway, add the error check
just in case.

v2: Rebase.
