[PATCH net-next] net: mhi: Make symbol 'mhi_wwan_ops' static

The sparse tool complains as follows:

drivers/net/mhi/net.c:385:23: warning:
 symbol 'mhi_wwan_ops' was not declared. Should it be static?

This symbol is not used outside of net.c, so marks it static.

Fixes: 13adac032982 ("net: mhi_net: Register wwan_ops for link creation")
