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 Signed-off-by: Mark Einon <mark.einon@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

 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 ?
