The interrupt status polling is unreliable, which can cause status events
to get lost. On all newer chips, txs-timeout is an indication that the
packet was either never sent, or never acked.
Fixes issues with inactivity polling.

When queueing packets, only the MT76_RESET flag of the primary PHY
is checked. If the primary PHY is scanning or changing channels, this can
lead to packet loss for tx on the second PHY.
Fix this by passing the phy to the .tx_queue_skb op and using it to check
the correct flag.

The ieee80211_queue_work function queues work into the mac80211
local->workqueue, which is widely used for mac80211 internal
work processes. In the mt76 driver, both the mt76-sido-status and
mt76-sdio-net threads enqueue workers to the workqueue with this
function. However, in some cases, when two workers are enqueued
to the workqueue almost simultaneously, the second worker may not
be scheduled immediately and may get stuck for a while.
This can cause timing issues. To avoid these timing
conflicts caused by worker scheduling, replace the worker
with an independent thread.
