    pipeline: fix realloc of uniform overrides array
    
    If we need to realloc the uniforms overrides array for a pipeline to
    insert a new override then we copy the old state into the new allocation
    for the entries surrounding the inserted entry.
    
    This patch fixes a mistake in how we copied the old entries that follow
    the inserted entry since we were actually copying to begining of the new
    allocation and potentially reading from beyond the extents of the old
    allocation.
