The 802.11 core statistics are retrieved from the core registers
but not stored. So the debug code was never triggered to give a
warning message on tx underruns or rx overflows. This patch fixes
this and assures the statistics are stored in the snapshot.

Disconnect flow may be invoked either from upper layer request,
or from event reported by the firmware.
In case of firmware event, driver need to release resources for the station but
not send another disconnect WMI command.
In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to
be issued for the firmware to perform disconnect on the MAC layer. Eventually,
event is expected to confirm MAC disconnect, but it is better to not wait for
firmware event and release station resources immediately. FW may fail to
report disconnect for various reasons, so one could not rely on event always reported.
Introduce parameter to distinguish 2 cases above to prevent double WMI command
issuing.
