wlan: Reset Rx last SSN after clear filter

Currently, when MSDU reorder info exists for a tid of station, then
after clear filter host last Rx packet sequence number SSN goes out
of sync with the hardware. Reason is in the period between set and
clear filter packets coming to device will be dropped at the firmware
because of the filter applied and host still has the last SSN before
set filter. Also RX packet's SSN will wrap around and start from zero
if SSN crosses 4096 in the period between set and clear filters.

After clear filter because of above reasons RX packet SSN in issue case
will be less than the host last RX SSN and when the difference is more
than threshold which in this case is 3000 packet gets dropped.

In this change reset the last Rx SSN to zero for the station's tid
MSDU reorder info if exists.
