macvlan: return correct error value
A MAC address must be unique among all the macvlan devices with the same
lower device. The only exception is the passthru [sic] mode,
which shares the lower device address.
When duplicate addresses are detected, EBUSY is returned when bringing
the interface up:
# ip link add macvlan0 link eth0 type macvlan
# read addr </sys/class/net/eth0/address
# ip link set macvlan0 address $addr
# ip link set macvlan0 up
RTNETLINK answers: Device or resource busy
Use correct error code which is EADDRINUSE, and do the check also
earlier, on address change:
# ip link set macvlan0 address $addr
RTNETLINK answers: Address already in use
