RDMA/core: Add umem "is_contiguous" and "start_dma_addr" helpers
In some cases drivers may need to check if a given umem is contiguous.
Add a helper function in core code so that drivers don't need to deal
with umem or scatter-gather lists structure.
Additionally add a helper for getting umem's start DMA address and use
it in other helper functions that open code it.
