afs: Use new netfs lib read helper API Make AFS use the new netfs read helpers to implement the VM read operations: - afs_readpage() now hands off responsibility to netfs_readpage(). - afs_readpages() is gone and replaced with afs_readahead(). - afs_readahead() just hands off responsibility to netfs_readahead(). These make use of the cache if a cookie is supplied, otherwise just call the ->issue_op() method a sufficient number of times to complete the entire request. Changes: v5: - Use proper wait function for PG_fscache in afs_page_mkwrite()[1]. - Use killable wait for PG_writeback in afs_page_mkwrite()[1]. v4: - Folded in error handling fixes to afs_req_issue_op(). - Added flag to netfs_subreq_terminated() to indicate that the caller may have been running async and stuff that might sleep needs punting to a workqueue.
