thunderbolt: Fix memory leak in margining_port_remove()
The dentry returned by debugfs_lookup() needs to be released by calling
dput() which is missing in margining_port_remove(). Fix this by calling
debugfs_lookup_and_remove() that combines both and avoids the memory leak.
Fixes: d0f1e0c2a699 ("thunderbolt: Add support for receiver lane margining")
