Christoph Hellwig 1335d6fd65 fore200e: devirtualize dma alloc calls ...

There is no need for an indirection before calling the dma alloc
routines now that we store a struct device in struct fore200e.

Also remove the pointless GFP_ATOMIC for the sbus case, and fix the
up the error handling by removing the 0 dma_addr test - some iommus
can return 0 as a perfectly valid bus address.
