[MiNT] [PATCH] Remove wrong debug message

[David Gálvez <dgalvez75@gmail.com>]

Alan, another one. Thank you.


Commit message:

When a device fails to initialize and it's physically removed, this
debug message shows bogus info. The device number will be shown in the
function usb_disconnect anyway.
