rds: store socket timestamps as ktime_t
rds is the last in-kernel user of the old do_gettimeofday() function. Convert it over to ktime_get_real() to make it work more like the generic socket timestamps, and to let us kill off do_gettimeofday(). A follow-up patch will have to change the user space interface to deal better with 32-bit tasks, which may use an incompatible layout for 'struct timespec'.
