[PATCH] net: nixge: Address compiler warnings when building for i386

[Moritz Fischer <mdf@kernel.org>]

Address compiler warnings reported by kbuild autobuilders
when building for i386 as a result of dma_addr_t size on
different architectures.

warning: cast to pointer from integer of different size
	[-Wint-to-pointer-cast]
