Subject: [PATCH] ocfs2: delete double assignment

Delete successive assignments to the same location. The two assignments are
simply identical.

A simplified version of Coccinelle semantic match that finds this problem is as
follows:

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>

Should the fist assignment be initializing the pv_minor field?
