The TX_RECOVERY_PENDING flag causes tg3_poll[_msix] to return early before doing much of its work. Tg3_reset_task() gets canceled when the configuration of the device is changing, which always results in a chip reset. When this happens, the TX_RECOVERY_PENDING flag may be left set, which would unnecessarily hinder tg3_poll from doing work. This patch fixes the problem.
