be updated to this slave's hwaddr in function:

But we didn't update the ctx->hwaddr, which is still the team's init hwaddr.
Later in the following functions:
lacp_port_set_mac()
lb_event_watch_port_added()
ab_hwaddr_policy_same_all_port_added()
they will set the first slave's hwaddr to team's init hwaddr(ctx->hwaddr).
This will cause that the first slave(most likely the active slave)'s hwaddr
changes to team dev's original hwaddr, and later back to its old hwaddr
again, which would make the LACPDUs have different Actor System IDs.
Fix it by updating ctx->hwaddr when set ctx->ifindex to new hwaddr.
Note that teamd_set_hwaddr() doesn't need this fix as it will set
ctx->hwaddr_explicit = true.
v2: update commit description, no code changes.
