Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw89: avoid to init mgnt_entry list twice when WoWLAN failed

If WoWLAN failed in resume flow, the rtw89_ops_add_interface() triggered

without removing the interface first. Then the mgnt_entry list init again,

causing the list_empty() check in rtw89_chanctx_ops_assign_vif()

useless, and list_add_tail() again. Therefore, we have added a check to

prevent double adding of the list.
