We use ppdu_sts to obtain channel information from hardware, to ensure
that the scan results have correct channel information. However, some of
ppdu_sts that is filtered by the to_self check is also needed for the scan
results. Therefore, we modify the filter part in front of CFO count.

wifi: iwlwifi: mvm: fix station link data leak
When we remove the station, we call iwl_mvm_sta_del() which
returns true if we cannot remove it from the firmware yet,
which happens if this is the station ID for the AP station
that's still used because the MAC is still associated.
However, we still must free the link data as the station is
only kept alive in the firmware, in mac80211 and driver the
data structures are destroyed.
To fix that, we need to make iwl_mvm_mld_free_sta_link()
track whether or not the station is still alive in FW, as
otherwise we might reuse the station ID in the meantime and
iwl_mvm_mld_rm_sta_from_fw() would reject the later delete
from the firmware. Add an argument to it for that. Then we
can use the return value of iwl_mvm_sta_del() for that to
fix the issue, and call iwl_mvm_mld_rm_sta_from_fw() only
if we need to not keep the station in FW.
