staging: dgap: remove useless variable
dgap_major_serial_registered and dgap_major_transparent_print_registered
could be checked whether a board is initialized.
But it doesn't need to check that variables becasue dgap module
isn't calling the dgap_cleanup_tty() without initializing
for a board completely.
