[][MAC80211][hostapd][Fix wds AP interface adding issue]

[Description]
Fix wds AP interface adding issue.

After hostapd creates a AP_VLAN interface, it adds the interface into
br-lan, and concurrently netifd also tries to add the interface into
br-lan, which might cause a race condition. In hostpad, linux_br_add_if
used to return -1 if ioctl return error.

A status check is added to see if the interface is correctly bridged
before linux_br_add_if return error.
