ARM: OMAP: DMA: Fix uninitialized channel flags
This has similar symptoms than 66c23551b1b774e2be3c7bdf91c0ebf2c7a3519e
where just omap_request_dma, omap_dma_link_lch and omap_dma_unlink_lch
can cause incorrect dump_stack(). Here it can happen if channel has been
used before and the channel flags variable holds old status.
