Subject: [PATCH 2/4] net/sysctl: remove leftover __user annotations on neigh_proc_dointvec*

Remove the leftover __user annotation on the prototypes for
neigh_proc_dointvec*.  The implementations already got this right, but
the headers kept the __user tags around.

Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler")
