cputime: Constify timeval_to_cputime(timeval) argument
Saw the following compiler warning on the linux-next tree:
kernel/itimer.c: In function 'set_cpu_itimer':
kernel/itimer.c:152:2: warning: passing argument 1 of 'timeval_to_cputime' discards 'const' qualifier from pointer target type [enabled by default]
...
timeval_to_cputime() is always passed a constant timeval in
argument, we need to teach the nsecs based cputime
implementation about that.
