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

[ Upstream commit 8cfa238a ]

ixgbevf_init_module() won't destroy the workqueue created by
create_singlethread_workqueue() when pci_register_driver() failed. Add
destroy_workqueue() in fail path to prevent the resource leak.

Similar to the handling of u132_hcd_init in commit f276e002
("usb: u132-hcd: fix resource leak")

Fixes: 40a13e24 ("ixgbevf: Use a private workqueue to avoid certain possible hangs")
