[PATCH -next] nfs: fix stub return type warnings

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxx>

Fix numerous repeated warnings by making the stub function
void instead of non-void:

fs/nfs/nfs4_fs.h: In function 'nfs4_unregister_sysctl':
fs/nfs/nfs4_fs.h:385:1: warning: no return statement in function returning non-void
