Subject: [PATCH] mt76: mt7615: clean up FWDL TXQ during/after firmware upload
Git-commit: 5abe8baf107eac8f1849408b353a792d5dd973ac
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
Since we don't clean that tx queue from the tx tasklet, we need to do it
after the firmware upload is done. This patch also adds a cleanup step during
the upload, to help reclaim memory faster.
Fixes unprocessed queued frames eating up memory long after the firmware
upload has already completed
