USB: pass mem_flags to dma_alloc_coherent
When I want to use my webcam, I get:
vvvvvvv
cheese: page allocation failure. order:5, mode:0x8004
Pid: 8100, comm: cheese Not tainted 2.6.30-rc2-wl-dirty #102
Call Trace:
[<ffffffff802c5d8e>] __alloc_pages_internal+0x3fe/0x520
[<ffffffff80210a20>] dma_generic_alloc_coherent+0x90/0x120
[<ffffffffa001c91e>] hcd_buffer_alloc+0xee/0x130 [usbcore]

[<ffffffffa0160ff6>] uvc_init_video+0x126/0x400 [uvcvideo]
[...]
Oddly, I remembered fixing this and putting in __GFP_NOWARN
because uvcvideo retries a smaller allocation. However, the
allocation function doesn't pass the gfp flags through to
dma_alloc_coherent so we still get the warning!
