gve: Fix stuck TX queue for DQ queue format
commit b03f15c0192b184078206760c839054ae6eb4eaa upstream.
gve_tx_timeout was calculating missed completions in a way that is only
relevant in the GQ queue format. Additionally, it was attempting to
disable device interrupts, which is not needed in either GQ or DQ queue
formats.
As a result, TX timeouts with the DQ queue format likely would have
triggered early resets without kicking the queue at all.
This patch drops the check for pending work altogether and always kicks
the queue after validating the queue has not seen a TX timeout too
recently.
