net: convert unicast addr list
This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.
