Subject: brcmfmac: remove setting IBSS mode when stopping AP

From: Chi-hsien Lin <[email protected]>

commit 9029679f66d976f8c720eb03c4898274803c9923 upstream.

Upon stopping an AP interface the driver disable INFRA mode effectively setting the interface in IBSS mode. However, this may affect other interfaces running in INFRA mode. For instance, if user creates and stops hostap daemon on virtual interface, then association cannot work on primary interface because default BSS has been set to IBSS mode in firmware side. The IBSS mode should be set when cfg80211 changes the interface.
