IPv6 address entry was not updated to use display_table_row which led to
a shifted line in table, as shown below:
$ iwctl station wlan0 show | head | sed 's| |.|g'
.................................Station:.wlan0................................
--------------------------------------------------------------------------------
..Settable..Property..............Value..........................................
--------------------------------------------------------------------------------
............Scanning..............no...............................................

............IPv4.address..........192.168.1.12.....................................
............IPv6.address........fdc3:541d:864f:0:96db:c9ff:fe36:b15............
............ConnectedBss..........cc:d8:43:77:91:0e................................
This patch aligns IPv6 address line with other lines in the table.
