net: addr_list: add exclusive dev_uc_add and dev_mc_add
This adds a dev_uc_add_excl() and dev_mc_add_excl() calls
similar to the original dev_{uc|mc}_add() except it sets
the global bit and returns -EEXIST for duplicat entires.
This is useful for drivers that support SR-IOV, macvlan
devices and any other devices that need to manage the
unicast and multicast lists.
v2: fix typo UNICAST should be MULTICAST in dev_mc_add_excl()
