qcacld-3.0: Remove get disconnect stats command from serialization

Currently in SAP mode, when host driver receives disconnect for
station, first it gets disconnect stats with serialization command
and then it sends delete peer command to fw. There is an issue with
this approach, if there are maximum number of clients are connected
to a SAP and all of these clients gets disconnected at the same
time, in that case there will be a disconnect stats command and
peer delete command in serialization, because of which serialization
queue gets full.

To address this issue, remove disconnect stats command from
serialization and send this command just before sending peer
delete command once peer delete command gets serialized.
