brd: warn on un-aligned buffer
Queue dma alignment limit requires users(fs, target, ...) of block layer to pass aligned buffer. So far brd doesn't support un-aligned buffer, even though it is easy to support it. However, given brd is often used for debug purpose, and there are other drivers which can't support un-aligned buffer too. So add warning so that brd users know what to fix.
