wifi: rt2x00: fix rt2800 watchdog function
The watchdog function is broken on rt2800 series SoCs. This patch
fixes the incorrect watchdog logic to make it work again.
1. Update current wdt queue index if it's not equal to the previous
index. Watchdog compares the current and previous queue index to
judge if the queue hung.
2. Make sure hung_{rx,tx} 'true' status won't be override by the
normal queue. Any queue hangs should trigger a reset action.
3. Clear the watchdog counter of all queues before resetting the
hardware. This change may help to avoid the reset loop.
4. Change hang check function return type to bool as we only need
to return two status, yes or no.
