tg3: use dma_alloc_coherent() instead of pci_alloc_consistent()

Using dma_alloc_coherent() permits to use GFP_KERNEL allocations instead
of GFP_ATOMIC ones. Its better when a machine is out of memory, because
this allows driver to sleep to get its memory and succeed its init,
especially when allocating high order pages.
