[PATCH linux-next] ARM/dma-mapping: replace kzalloc() and vzalloc() with kvzalloc()

[yang.guang5 at zte.com.cn]

From: Yang Guang <yang.guang5 at zte.com.cn>
using kvzalloc() simplifies the code by avoiding the 
use of different memory allocation functions for different 
situations, making the code more uniform and readable.
