arch/alpha/kernel/sys_ruffian.c: Use DIV_ROUND_CLOSEST
The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d
but is perhaps more readable.
The semantic patch that makes this change is as follows:

@depends on haskernel@
expression x,__divisor;

- (((x) + ((__divisor) / 2)) / (__divisor))
+ DIV_ROUND_CLOSEST(x,__divisor)
