[PATCH master] sandbox: dma: fix recursive dependency between headers

[Ahmad Fatoum]

If <dma.h> includes <linux/kernel.h> via <asm/dma.h>, it will end up
including <linux/slab.h>, which in turn includes <dma.h>.

This leads to use of symbols before definition, so remove the
<linux/kernel.h> definition.

Fixes: 9b12861830e0 ("include: linux/slab: use dma_alloc for kmalloc")
