ipw2200: firmware DMA loading rework
Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure for ipw2200 firmware loading in kernel 2.6.30. High order allocation is likely to fail and should always be avoided. The patch fixes this problem by replacing the original order-6 pci_alloc_consistent() with an array of order-1 pages from a pci pool. This utilized the ipw2200 DMA command blocks (up to 64 slots). The maximum firmware size support remains the same (64*8K).
