Turns out the only flags field was in the pd, and pd->flags only has one
flag, currently, indicating that the global_dma_rkey is in use.  Since the
kernel side only sends up the global_dma_rkey if that flag is set, I just
dropped the PD_FLAGS attribute in both patch series.  If pd flags grow, we
can add it, but I don't expect that.
