Besides the point of splitting out the iov_iter_extract* conversion this
seems to ignore pNFS. You also need to check the layout driver for the
current file range and propagate P2P support or lack of through that.

Note that the block-style layouts can also trivially support P2P and not
just RPC-based ones.
