In the previous implementation connected STA performs OBSS scan according to requests from its 20/40 MHz AP. However STA checks only 40 MHz intolerance subfield from HT Capabilities element in scan results. Meanwhile, as per IEEE Std 802.11-2016, 11.16.12, STA should check overlapping BSSs as well. Note that all the required code to check overlapping BSSs did already exist for AP mode since AP does those checks properly before operating as 20/40 MHz BSS in the 2.4 GHz band. Use that existing code by replace existing 40 MHz intolerance check in sme_proc_obss_scan() with the new shared helper function check_bss_coex_40mhz().
