Subject: [PATCH 5.9 073/152] iwlwifi: mvm: use the HOT_SPOT_CMD to cancel an AUX ROC

From: Emmanuel Grumbach <emmanuel.grumbach@...el.com>

[ Upstream commit fb8d1b6e97980057b7ebed444b8950e57f268a67 ]

The ROC that runs on the AUX ROC (meaning an ROC on the STA vif),
was added with the HOT_SPOT_CMD firmware command and must be
cancelled with that same command.
