mtd: spi-nor: fix memory leak when using debugfs_lookup()
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To solve this, remove the
lookup and create the directory on the first device found, and then
remove it when the module is unloaded.
