rose: Set the destination address in rose_header
Not setting the destination address is a bug that I suspect causes no
problems today, as only the arp code seems to call dev_hard_header and
the description I have of rose is that it is expected to be used with a
static neigbour table.
I have derived the offset and the length of the rose destination address
from rose_rebuild_header where arp_find calls neigh_ha_snapshot to set
the destination address.
