In function probe_disk_log_file(), handler 'dir'
 returned by opendir() is not released before
 function return and results in memory leakage.

Yonghua Huang 7909cf31c6 dm: fix potential program crash issue in disk_logger
detection of any error in 'probe_disk_log_file()'
  calling 'pr_err()' will cause 'write_to_disk()' function
  being called recursively infinitely, as pr_err will
  call write_to_disk() and trap to probe_disk_log_file() again,
  hence program will crash finally.

  This patch fix above issue by using printf instead of pr_err,
  as printf outputs to console directly.

disk-logger used to save persistent log as file in disk.

2-9 to 3-10 ...
