commit b78a4932f5 upstream.
The check whether the IBSS is active and can be removed should be
performed before deinitializing the fields used for the check/search.
Otherwise, the configured BSS will not be found and removed properly.
To make it more clear for the future, rename sdata->u.ibss to the
local pointer ifibss which is used within the checks.
