Christophe JAILLET 3ebe69c0c3 ocfs2: constify struct ocfs2_lock_res_ops
"struct ocfs2_lock_res_ops" are not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security.

In order to do it, "struct ocfs2_lock_res" also needs to be adjusted to
this new const qualifier.

On a x86_64, with allmodconfig:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  83038	   2632	    400	  86070	  15036	fs/ocfs2/dlmglue.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  83806	   1992	    272	  86070	  15036	fs/ocfs2/dlmglue.o
