[PATCH] headers_check: reduce user-visible noise in <linux/nfs_fs.h>

We don't need any of this crap included from the user-visible part of nfs_fs.h
-- remove it all.

In fact, we probably don't need anything but NFS_SUPER_MAGIC to be defined; is
there any need for anything else?  And magic numbers should probably move to
<linux/magic.h> rather than being strewn across various fs-specific include
files which exist in userspace for solely that purpose.

With this patch, 'make header_check' works again at least on PowerPC.
