patches: patches: Restrict MTU changes to struct net_device

The struct ieee80211_hw got a max_mtu element, but no min_mtu element.
This spatch was also applied to this structure accidentally.

This adds the type to make sure this spatch is only applied to mtu_min
and mtu_max attributes on the net_device structure.
