tulip: xircom_cb: Convert #ifdef DEBUG blocks and enter/leave uses
Change the blocks that are guarded by #if DEBUG to be #if defined DEBUG && DEBUG > 1 so that pr_debug can be used later. Remove enter/leave macros and uses. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
