replace DIV_ROUND with DIV_ROUND_CLOSEST
The Linux-compatible macro DIV_ROUND_CLOSEST is a bit more flexible and safer than DIV_ROUND. For example, foo = DIV_ROUND_CLOSEST(x, y++) works expectedly, but foo = DIV_ROUND(x, y++) does not. (y is incremented twice.) Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
