Subject: [PATCH] debugfs.ocfs2: Fix the error on devices with sector size 4096

Debugfs.ocfs2 can not work on devices with sector size 4096,
e.g.
 # debugfs.ocfs2 -s 1 /dev/sdd
 open: I/O error on channel Can't get the blocksize from the device by the num 1
 # blockdev --getss /dev/sdd
 4096

we should remove these line hard code, then debugfs.ocfs2 works on
different sector size devices.
