drivers: net: ionic: add missed debugfs cleanup to ionic_probe() error path

The ionic_setup_one() creates a debugfs entry for ionic upon
successful execution. However, the ionic_probe() does not
release the dentry before returning, resulting in a memory
leak.

To fix this bug, we add the ionic_debugfs_del_dev() to release
the resources in a timely manner before returning.
