: Fix thinko in macvlan_transfer_operstate()

Fix a minor thinko in macvlan. The bug is uncritical, so this doesn't need to go in 2.6.24.

[MACVLAN]: Fix thinko in macvlan_transfer_operstate()

When the lower device's carrier is off, the macvlan devices's carrier state should be checked to decide whether it needs to be turned off. Currently the lower device's state is checked a second time.

This still works, but unnecessarily tries to turn off the carrier when its already off.
