[PATCH 2/3] lockd: Switch linux/nfs.h to linux/nfs_fh.h

lockd references "struct nfs_fh" but none of the other definitions
in linux/nfs.h. That header also pulls in cred.h, several sunrpc
headers, and uapi/linux/nfs.h, none of which lockd needs. A new
linux/nfs_fh.h provides "struct nfs_fh" and its helpers without the
rest of that surface.

Switch lockd's xdr.h to linux/nfs_fh.h, and drop the now-redundant
linux/nfs.h includes from svc.c and trace.h.
