[PATCH net] net: socket: Make unnecessarily global sockfs_setattr() static

[Tobias Klauser]

Make sockfs_setattr() static as it is not used outside of net/socket.c

This fixes the following GCC warning:
net/socket.c:534:5: warning: no previous prototype for ‘sockfs_setattr’ 
[-Wmissing-prototypes]

Fixes: 86741ec25462 ("net: core: Add a UID field to struct sock.")
