staging: Use GFP_ATOMIC when a lock is held

In each case, the containing function is only called from one place, where
a spin 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
    when any
  GFP_KERNEL@p
 ... when any
}

@locked@
identifier gfp.fn;
@@

spin_lock(...)
... when != spin_unlock
fn(...)

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

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