ath10k: remove the max_sched_scan_reqs value
The struct cfg80211_wowlan of NET_DETECT WoWLAN feature share the same struct cfg80211_sched_scan_request together with scheduled scan request feature, and max_sched_scan_reqs of wiphy is only used for sched scan, and ath10k does not support scheduled scan request feature, so ath10k does not set flag NL80211_FEATURE_SCHED_SCAN_RANDOM_MAC_ADDR, but ath10k set max_sched_scan_reqs of wiphy to a non zero value 1, then function nl80211_add_commands_unsplit of cfg80211 will set it support command NL80211_CMD_START_SCHED_SCAN because max_sched_scan_reqs is a non zero value, but actually ath10k not support it, then it leads a mismatch result for sched scan of cfg80211, then application shill found the mismatch and stop running case of MAC random address scan and then the case fail. After remove max_sched_scan_reqs value, it keeps match for sched scan and case of MAC random address scan pass. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029. Tested with QCA6174 PCIe with firmware WLAN.RM.4.4.1-00110-QCARMSWP-1.
