SME: Fix OBSS scan result processing for 20/40 MHz co-ex report 

The 40 MHz intolerant bit needs to be checked before skipping the BSS
based on the channel already being in the lost (which could have
happened due to another BSS that does not indicate 40 MHz intolerant).
This fixed the 20/40 MHz co-ex report to indicate 20 MHz request
properly if there are both 40 MHz tolerant and intolerant BSSes on the
same channel.
