Wlan: Invalid WLAN driver reloading fix

Frames count handled by previous interrupt was not set properly, right
after correct resync finished. Sometimes empty interrupt may come in,
but previous number of handled frame did not set ptoperly, DXE WLAN
driver think successive empty interrupt generated. DXE descriptor dump
log is not reasonable, reduce dump descriptors as just for needed
