Subject: [PATCH 3.19 44/75] iwlwifi: mvm: Fix ROC removal

3.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrei Otcheretianski <andrei.otcheretianski@...el.com>

commit 833d9b9785b3eedfaf2c869a6a63deba88058599 upstream.

iwl_mvm_stop_roc removes TE only if running flag is set. This is not correct
since this flag is only set when the TE is started.
This resulted in a TE not being removed, when mac80211 believes that there are
no active ROCs.

Fixes: bf5da87f60a9 ("iwlwifi: mvm: add remove flow for AUX ROC time events")
