Staging: lustre: Remove typedef ldlm_ns_hash_def_t

The linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedef for
ldlm_ns_hash_def_t. Also, the name of the struct is changed to drop
the _t, to make the name look less typedef-like.

This is done using Coccinelle. Semantic patch used to detect this
case is as follows:

@tn1@
type td;
@@

typedef struct { ... } td;

@script:python tf@
td << tn1.td;
tdres;
@@

coccinelle.tdres = td;

@@
type tn1.td;
identifier tf.tdres;
@@

-typedef
 struct
+  tdres
   { ... }
-td
 ;

@@
type tn1.td;
identifier tf.tdres;
@@
-td
+ struct tdres
