i40e: Fix error handling in i40e_init_module()
i40e_init_module() won't free the debugfs directory created by
i40e_dbg_init() when pci_register_driver() failed. Add fail path to
call i40e_dbg_exit() to remove the debugfs entries to prevent the bug.
i40e: Intel(R) Ethernet Connection XL710 Network Driver
i40e: Copyright (c) 2013 - 2019 Intel Corporation.
debugfs: Directory 'i40e' with parent '/' already present!
Fixes: 41c445ff0f48 ("i40e: main driver core")
