Marco Casaroli 3619c557a6 fs/v9fs: Report the end of a directory as the end, not as an error. 
At the end of a directory the 9P server returns no entries.
v9fs_client_convertdir() then failed with -EIO, so readdir() returned
NULL with errno set to EIO at the end of every directory.  A program
that checks errno after readdir() reports an I/O error.

Return -ENOENT when the server returns no entries.  The VFS turns that
into a clean end of directory.  Also check the space for the fixed part
of an entry against the bytes left after head, not against the whole
buffer.
