[Mesa-dev] [PATCH] nir: Check if u_vector_init() succeeds

[Topi Pohjolainen]

However, it only fails when running out of memory. Now, if we
are about to check that, we should be consistent and check
the allocation of the worklist as well.

On the other hand there are other places where we don't check
for allocation failures. Therefore I'm not sure if we bother
here either. Coverity complains but I can mark it as ignored
the same.
