In line 334, 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() before
line 397 to release the resources before the function returns.

Fixes: 0de38d9f1dba ("ionic: extract common bits from ionic_probe")
