wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is active
When there's an active link in a non-station vif, the station vif is
not allowed to enter EMLSR
Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule
an exit from EMLSR worker, but the worker cannot run before the
activation of the non-BSS link, as ieee80211_remain_on_channel already
holds the wiphy mutex.
Handle that by explicitly calling ieee80211_set_active_links()
to leave EMLSR, and then doing iwl_mvm_block_esr() only for
consistency and to avoid re-entering it before ready.
Note that a call to ieee80211_set_active_links requires to release the
mvm mutex, but that's ok since we still hold the wiphy lock. The only
thing that might race here is the ESR_MODE_NOTIF, so this changes its
handler to run under the wiphy lock.
