stable inclusion
from stable-v5.10.156
commit 6b23a4b252044e4fd23438930d452244818d7000
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7MCG1

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=6b23a4b252044e4fd23438930d452244818d7000

--------------------------------

[ Upstream commit d349e9be ]

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: 1738cd3e ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
