drivers/isdn/hardware/mISDN: Use GFP_ATOMIC when a lock is held

The function inittiger is only called from nj_init_card, where a lock is held.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@gfp exists@
identifier fn;
position p;
@@

fn(...) {
 ... when != spin_unlock_irqrestore
     when any
 GFP_KERNEL@p
 ... when any
}

@locked@
identifier gfp.fn;
@@

spin_lock_irqsave(...)
...  when != spin_unlock_irqrestore
fn(...)

@depends on locked@
position gfp.p;
@@

- GFP_KERNEL@p
+ GFP_ATOMIC
// </smpl>
