net: hns3: add struct netdev_queue debug info for tx timeout

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

When there is a tx timeout, we can tell if the driver or stack
has stopped the queue by looking at state field, and when was
the last packet transmited by looking at trans_start field.

This patch adds the above two cases to the logging of tx timeout.
