Eric van Gyzen 4cf66812ea nanosleep: plug a kernel memory disclosure 
nanosleep() updates rmtp on EINVAL.  In that case, kern_nanosleep()
has not updated rmt, so sys_nanosleep() updates the user-space rmtp
by copying garbage from its stack frame.  This is not only a kernel
memory disclosure, it's also not POSIX-compliant.  Fix it to update
rmtp only on EINTR.
