wifi: rtw89: avoid to init mgnt_entry list twice when WoWLAN failed
[ Upstream commit 2f7667675df1b40b73ecc53b4b8c3189b1e5f2c1 ]
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.
