crypto: ccree - Remove debugfs when platform_driver_register failed
[ Upstream commit 4f1c596df706c9aca662b6c214fad84047ae2a97 ]
When platform_driver_register failed, we need to remove debugfs,
which will caused a resource leak, fix it.
Failed logs as follows:
[ 32.606488] debugfs: Directory 'ccree' with parent '/' already present!
