dma-mapping: Add check if IOVA can be used

This patch adds a check if IOVA can be used for the specific
transaction.

In the new API a DMA mapping transaction is identified by a
struct dma_iova_state, which holds some recomputed information
for the transaction which does not change for each page being
mapped.
