By default the driver uses the 1M and 6M rate (0x0) for data frames in
2 GHz and 5/6 GHz bands respectively. But the rate that might not AP
supported. Therefore, We modify the data lowest rate according to the
lowest of AP supported rate.

The register-based H2C/C2H are used to exchange information between driver
and firmware, but only apply to narrow area because its data size is
smaller than regular packet-based H2C/C2H.
This kind of H2C/C2H must be paired. To identify if any H2C/C2H is missing,
update counters to help diagnose this kind of problems.

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.
