[PATCH 2/2] NFS: honour preferred rsize/wsize reported by server.

[NeilBrown <neilb@suse.de>]

When a filesystem is mounted with ASCII mount options, and no rsize
or wsize is given, the client should default to using the preferred
sizes reported in the FSINFO request.
However it does not.  These values are initialised to
NFS_MAX_FILE_IO_SIZE and as they are now non-zero, the default does
not get applied.

So initialise to 0 thus allowing appropriate defaults to apply.
