Christoph Hellwig 5ef990f06b IB/core: remove ib_get_dma_mr 
We now only use it from ib_alloc_pd to create a local DMA lkey if the
device doesn't provide one, or a global rkey if the ULP requests it.

This patch removes ib_get_dma_mr and open codes the functionality in
ib_alloc_pd so that we can simplify the code and prevent abuse of the
functionality.  As a side effect we can also simplify things by removing
the valid access bit check, and the PD refcounting.

In the future I hope to also remove the per-PD global MR entirely by
shifting this work into the HW drivers, as one step towards avoiding
the struct ib_mr overload for various different use cases.
