arch/sparc/mm: Use GFP_KERNEL

GFP_ATOMIC is not needed here, as evidenced by the other two uses of
GFP_KERNEL in the same 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>
