Subject: staging: comedi: fix clean-up of comedi_class in comedi_init()

There is a clean-up bug in the core comedi module initialization functions, comedi_init(). If the comedi_num_legacy_minors module parameter is non-zero (and valid), it creates that many "legacy" devices and registers them in SysFS. A failure causes the function to clean up and return an error. Unfortunately, it fails to destroy the "comedi" class that was created earlier. Fix it by adding a call to class_destroy(comedi_class) at the appropriate place in the clean-up sequence.
