fsck:fix double free of exfat pointer #55

Closed yijiangqiu1 closed 2 years ago

yijiangqiu1 commented 2 years ago 
  in function init_exfat(exfat,bs),if it fails to calloc memory,it will call function free_exfat and return -ENOMEM. Thus it will goto err in main function and call free_exfat(exfat) again.
  As follows:
       main
         ->init_exfat(exfat,bs)
           ->free_exfat(exfat)
             return -ENOMEM
         ->free_exfat(exfat)
