    LinuxKPI: 802.11: remove special handling for (*ic_scan_curchan)
    
    Remove the originally disabling of (*ic_scan_curchan), which for iwlwifi
    was not needed.  The condition always only was approximate.
    
    A set IEEE80211_FEXT_SCAN_OFFLOAD will still prevent net80211 from sending
    probe_reqs if handled by driver/firmware.
    ic_scan_curchan will re-arm the timer to switch channels for drivers which
    need it (e.g., rtw88, but that again is a NOP for iwlwifi).
    
    So enabling ic_scan_curchan should not have further side effects for iwlwifi
    but allow other drivers to work better.
