time: remove timespec_add_safe()
All references to timespec_add_safe() now use timespec64_add_safe().
The plan is to replace struct timespec references with struct timespec64
throughout the kernel as timespec is not y2038 safe.
Drop timespec_add_safe() and use timespec64_add_safe() for all
architectures.
