zhengbin 9176ab1b84 time: Validate user input in compat_settimeofday() 
The user value is validated after converting the timeval to a timespec, but
for a wide range of negative tv_usec values the multiplication overflow turns
them in positive numbers. So the 'validated later' is not catching the
invalid input.
