batman-adv: ensure u16 aligned mac address in structs

An u8 array in structures have a natural alignment of only 1 byte. An
u8[ETH_ALEN] array must therefore be assumed to only be 1 byte aligned. But
many etherdevices.h functions are requiring a 2 byte (u16) alignment.

All these addresses were either on the start of a struct or after a struct
member which required at least an alignment of 2 byte. Still, annote all
u8[ETH_ALEN] arrays on the stack as __aligned(2) to make sure that this
assumption isn't broken by other modifications inside the structs.
