Fix up dma_alloc_coherent with 64bit DMA masks on i386.

Cset 1.808 in 2.4 never got propagated forward to 2.5
It's pretty much the same fix as below (s/!=/</), but with the following
changes
- This was a patch to pci_alloc_consistant(), which now seems to be
  dma_alloc_coherent()
- Removal of the u32 cast
