Limit sleep_millisecs to minimum 10

According to the former KSM controller, ksmtuned, 10 should be the
minimum value for sleep_millisecs:

  48 sleep=$[KSM_SLEEP_MSEC * 16 * 1024 * 1024 / total]
  49 [ $sleep -le 10 ] && sleep=10      <---- 10 is the minimum
  50 debug sleep $sleep

Systems with a low sleep_millisecs number will run ksmd daemon without
interruption, causing a very high cpu time consumption.

This patch limits sleep_millisecs to the minimum of 10.
