USB: host: uhci: remove dentry pointer for debugfs
There is no need to keep the dentry pointer around for the created
debugfs file, as it is only needed when removing it from the system.
When it is to be removed, ask debugfs itself for the pointer, to save on
storage and make things a bit simpler.
And, no one noticed that a __maybe_unused dentry * in uhci_start()
really was unused, so remove that as it's obviously not needed, and
hasn't been for quite some time.
