Subject: [PATCH 019/104] hostapd: MLO: display link details in status command

Currently, link id and number of link details of a MLD AP interface is not
displayed in status command of hostapd_cli.

Add changes to display the link id and number of link details.

The details would be seen as below for a MLD AP interface:

$ hostapd_cli -i wlan0 status | grep link
num_links=1
link_id=0
link_addr=AA:BB:CC:DD:EE:FF

$ hostapd_cli -i wlan1 status | grep link
num_links=2
link_id=0
link_addr=AA:BB:CC:DD:EE:FF
partner_link_id=1
partner_link_addr=AA:BB:CC:DD:EE:AA

The above details would not be displayed for non-MLD AP interfaces.
