net: devmem: use memory provider helpers for net_iovs

Browse source

Use public memory-provider helpers for DMA address storage and page-pool
association instead of open-coding page_pool state and accounting.

Zero the net_iov array because net_mp_niov_set_page_pool() ORs
PP_SIGNATURE into pp_magic. Reject DMA addresses that cannot be
represented in net_iov metadata.
