[PATCH 1/1] arm :omap :DMA: fix a bug on reserving the omap SDMA channels

[ahemaily at gmail.com]

From: ahemaily <ahemaily at gmail.com>

The variable  dma_lch_count  used for comparison  (omap_dma_reserve_channels <= dma_lch_count)
before it initialized to the value from omap_dma_dev_attr : d->lch_count.

I change the place of dma_lch_count initialization to be before the comparison.
