Merge branch 'ipv6-fix-temporary-address-not-removed-correctly'

Hangbin Liu says:

====================
ipv6: fix temporary address not removed correctly

Currently the temporary address is not removed when mngtmpaddr is deleted
or becomes unmanaged. The patch set fixed this issue and add a related
test.

v2:
1) delete the tempaddrs directly instead of remove them in  addrconf_verify_rtnl(Sam Edwards)
2) Update the test case by checking the address including, add Sam in SOB (Sam Edwards)
