[PATCH][net-next] net: remove empty inet_exit_net

[Li RongQing]

Pointer members of an object with static storage duration, if not
explicitly initialized, will be initialized to a NULL pointer. The
net namespace API checks if this pointer is not NULL before using it,
it are safe to remove the function.
