[PATCH] mmc: sh_mmcif: correctly report success when obtaining DMA channels

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

The debug message could still report success when getting the channels
was OK but configuring them failed. This actually caused a minor detour
when debugging DMA problems, so make sure the success is only reported
when the channels are really ready-to-use.
