net/rose: Use GFP_ATOMIC
The other calls to kmalloc in the same function use GFP_ATOMIC, and indeed
two locks are held within the body of the function.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@ identifier f; @@
*f(...,GFP_ATOMIC,...)
... when != spin_unlock(...)
when != read_unlock(...)
when != write_unlock(...)
when != read_unlock_irq(...)
when != write_unlock_irq(...)
when != read_unlock_irqrestore(...)
when != write_unlock_irqrestore(...)
when != spin_unlock_irq(...)
when != spin_unlock_irqrestore(...)
*f(...,GFP_KERNEL,...)
// </smpl>
