staging: et131x: use dma_alloc... instead of pci_alloc... 

Use dma_allocs instead of pci_allocs, so we can use GFP_KERNEL
allocations.

Also removed this item from the TODO list

TODO:
- Use of kmem_cache seems a bit unusual
- Use dma_alloc_... in place of pci_alloc_...
- It's too late stopping the tx queue when there is no room for the current packet. The condition should be detected for the next packet.
- PCI_VDEVICE ?
