Add support for HT STA to report 40 MHz intolerance to the associated AP. A HT station generates a report (20/40 BSS coexistence) of channel list if it finds a non-HT capable AP or a HT AP which prohibits 40 MHz transmission (i.e., 40 MHz intolerant bit is set in HT capabilities IE) from the scan results. Parse the OBSS scan parameter from Beacon or Probe Response frames and schedule periodic scan to generate 20/40 coexistence channel report if requested to do so. This patch decodes Scan Interval alone from the OBSS Scan Parameters element and triggers scan on timeout.
