[PATCH next v3 2/3] ipvlan: mode is u16

[Mahesh Bandewar]

From: Mahesh Bandewar <mahe...@google.com>

The mode argument was erronusly defined as u32 but it has always
been u16. Also use ipvlan_set_mode() helper to set the mode instead
of assigning directly. This should avoid future erronus assignments /
updates.
