#1579730 — [PATCH 4.9 33/60] nl80211: Fix mesh HT operation check

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

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

From: Masashi Honma <masashi.honma@gmail.com>

commit fd551bac4795854adaa87bad7e5136083719802b upstream.

A previous change to fix checks for NL80211_MESHCONF_HT_OPMODE
missed setting the flag when replacing FILL_IN_MESH_PARAM_IF_SET
with checking codes. This results in dropping the received HT
operation value when called by nl80211_update_mesh_config(). Fix
this by setting the flag properly.
