[PATCH] qla1280 update

I am attaching the latest patch for qla1280, which includes Andrew's and
James' patches (modulo the 64 bit enable part) as well changes to make
it handle pci_set_dma_mask() correctly and switch to only use one of the
two SCSI command issuing versions depending on whether the driver is
compiled for 64 or 32 bit DMA. The old code effectively did this anyway,
but with this change it is no longer compiling in the part not used.
