Subject: [PATCH net] selftests: bonding: do not set port down when adding to bond

Similar to commit be809424659c ("selftests: bonding: do not set port down
before adding to bond"). The bond-arp-interval-causes-panic test failed
after commit a4abfa627c38 ("net: rtnetlink: Enslave device before bringing
it up") as the kernel will set the port down _after_ adding to bond if setting
port down specifically.

Fix it by removing the link down operation when adding to bond.

Fixes: 2ffd57327ff1 ("selftests: bonding: cause oops in bond_rr_gen_slave_id")
