RDMA/umem: Support an explicit DMA direction other than DMA_BIDIRECTIONAL
Add a dma_dir field to struct ib_umem to record the direction chosen at
map time and reuse it at unmap. Thread an explicit dma_data_direction
parameter through the internal pinning helpers so each caller can supply
the direction that matches the device's actual access pattern.
All existing callers still pass DMA_BIDIRECTIONAL, so this is a pure
mechanism addition with no behavioural change.
