net: ena: Fix error handling in ena_init()
[ Upstream commit d349e9be5a2c2d7588a2c4e4bfa0bb3dc1226769 ]
The ena_init() won't destroy workqueue created by
create_singlethread_workqueue() when pci_register_driver() failed.
Call destroy_workqueue() when pci_register_driver() failed to prevent the
resource leak.
Fixes: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
