Mark Johnston 6c7828a280 Avoid CPU migration in dtrace_gethrtime() on x86. 
dtrace_gethrtime() may be called outside of probe context, and in
particular, from the DTRACEIOC_BUFSNAP handler.

Disable interrupts rather than using sched_pin() to help ensure that
we don't call any external functions when in probe context.
