bonding: reset bond's flags when down link is P2P device
When adding a point to point downlink to the bond, we neglected to reset
the bond's flags, which were still using flags like BROADCAST and
MULTICAST. Consequently, this would initiate ARP/DAD for P2P downlink
interfaces, such as when adding a GRE device to the bonding.
To address this issue, let's reset the bond's flags for P2P interfaces.
Before fix:
7: gre0@NONE: <POINTOPOINT,NOARP,SLAVE,UP,LOWER_UP> mtu 1500 qdisc noqueue master bond0 state UNKNOWN group default qlen 1000
link/gre6 2006:70:10::1 peer 2006:70:10::2 permaddr 167f:18:f188::
8: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/gre6 2006:70:10::1 brd 2006:70:10::2
inet6 fe80::200:ff:fe00:0/64 scope link
valid_lft forever preferred_lft forever
