wifi: iwlwifi: mvm: Remove few redundant 6 GHz scan chan params

- iwl_mvm_scan_umac_chan_flags_v2() computes channel params flags
  that are only relevant for 2.4/5 GHz scan, explicitly clear
  the flags for 6 GHz scan.
- n_aps_override[0] and n_aps_override[1] are not relevant for
  6 GHz scan, remove them.
