nanosleep: Pass NULL when rem == NULL on ports with __TIMESIZE != 64
On ports with __TIMESIZE != 64 the remaining time argument always receives pointer to struct __timespec64 instance. This is the different behavior when compared to 64 bit versions of clock_nanosleep and nanosleep functions, which receive NULL. To avoid any potential issues, we also pass NULL when *rem pointer is NULL. Reported-by: Andreas Schwab <schwab@suse.de> Reviewed-by: Alistair Francis <alistair.francis@wdc.com>
