USB: host: isp116x: 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.
