[PATCH net-next 1/1] driver: macvlan: Remove duplicated IFF_UP condition check in macvlan_forward_source

[PATCH net-next 1/1] driver: macvlan: Remove duplicated IFF_UP condition check in macvlan_forward_source

[fgao]

From: Gao Feng <gfree.wind@gmail.com>

The function macvlan_forward_source_one has already checked the flag
IFF_UP, so needn't check it outside in macvlan_forward_source too.

 v2: Remove the IFF_UP check in macvlan_forward_source instead of macvlan_forward_source_one
