Subject: mwifiex: fix IBSS data path issue.
From: chunfan chen <jeffc@xxxxxxxxxxx>
commit dc386ce76dedaeeaaf006fceb6ed8cf2e20ff026 upstream.
The port_open flag is not applicable for IBSS mode. IBSS data
path was broken when port_open flag was introduced.
This patch fixes the problem by correcting the checks.
Fixes: 5c8946330abfa4c ("mwifiex: enable traffic only when port is open")
