iavf: Fix error handling in iavf_init_module()
The iavf_init_module() won't destroy workqueue when pci_register_driver()
failed. Call destroy_workqueue() when pci_register_driver() failed to
prevent the resource leak.
Similar to the handling of u132_hcd_init in commit f276e002793c
("usb: u132-hcd: fix resource leak")
Fixes: 2803b16c10ea ("i40e/i40evf: Use private workqueue")
