[PATCH] 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 wants to be
   dma_alloc_coherent()
 - Removal of the u32 cast
