*Arguments : none
*
*Return : do wear-levelling result;
* = 0 do wear-levelling successful;
* = -1 do wear-levelling failed.
*
*Notes : The erase cycle of a physical block is limited, if the erase cycle overun this
* limit, the physical block may be invalid. so a policy is needed to equate the
* millions of erase cycles to ervery physical block.
