cputime: Fix nsecs_to_cputime() return type cast
Even though nsec based cputime_t maps to u64, nsecs_to_cputime() must return a cputime_t value. We want to enforce this kind of cast in order to track down buggy manipulations of cputime_t such as direct access of its values under wrong assumptions on its backend type (nsecs, jiffies, etc...) by core code.
