Christopher Wiley - Oct. 10, 2012, 9:51 p.m.
Respond to AP triggered association failures by locally aborting the
association process.  For instance, certain enterprise AP's return
status code 17 (too many STAs) and reject association requests when a
particular AP has too many associated devices.  Locally aborting the
association process lets wpa_supplicant begin roaming immediately rather
than waiting for the authentication timeout to fire.

This change duplicates similar behavior that occurs when the driver
supports SME.
