[90/93] iwlwifi: Fix to set correct ht configuration

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Wey-Yi Guy <wey-yi.w.guy@intel.com>

commit 098dfded5b1b09927995e89c6d689f85a0f53384 upstream.

iwl_set_rxon_ht() only get called in iwl_post_associate(); which cause
possible incorrect ht configuration. Adding the call in iwl_mac_config() if
IEEE80211_CONF_CHANGE_CHANNEL flag is set to re-configure and send rxon
command.
