Commit a99d876a0f58 ("node_device: Use automatic mutex management") replaced the
locking mechanism and accidentally removed the comment with the reason why the
lock is taken. The reason was to "ensure only a single thread can query mdevctl
at a time", but this reason is no longer valid or maybe it never was. Therefore,
let's remove this lock and add a comment to `mdevCtl` what it protects.
