nfs: rename members of nfs_pgio_data
Rename "verf" to "writeverf" and "pages" to "page_array" to prepare for merge of nfs_pgio_data and nfs_pgio_header. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Weston Andros Adamson <dros@primarydata.com> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
