net: netsec: use dma_addr_t for storing dma address
On targets that have different sizes for phys_addr_t and dma_addr_t,
we get a type mismatch error:
drivers/net/ethernet/socionext/netsec.c: In function 'netsec_alloc_dring':
drivers/net/ethernet/socionext/netsec.c:970:9: error: passing argument 3 of 'dma_zalloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]
The code is otherwise correct, as the address is never actually used as a
physical address but only passed into a DMA register. For consistently,
I'm changing the variable name as well, to clarify that this is a DMA
address.
