A device should not be able to be used concurrently both by

dgap_driver_start and dgap_Major_Control_Registered are used
to keep status of initialization of the driver as a whole and its "Major Control".
But the code that checks them is executed once on module init/unload.
That makes no sense in these variables as far as their values are predictable
at any time.

Also "dgap_downld" device was removed, while
device_destroy(MKDEV(DIGI_DGAP_MAJOR, 1)) is still in dgap_cleanup_module().
The patch removes it by the way.
