Reduce number of iterations used for calibrating ICR read loop.  The
new number of iteration still gives the same ICR latency as before,
tested on Intel SandyBridge and Haswell machines, and on AMD.  But it
significantly reduces the unneeded pause on boot in some VMs, from ~10
secs to less then 1 sec.  It was reported to occur in bhyve on AMD
host.
