[PATCH 1/4] VMCI: Remove redundant error check

[Peter Senna Tschudin]

Remove double checks, and move the call to pr_devel to the
first check. The simplified version of the coccinelle semantic
patch that fixes this issue is as follows:

// <smpl>
@@
expression E; identifier pr; expression list es;
@@
for(...;...;...){
...
-	if (E) break;
+	if (E){
+		pr(es);
+		break;
+	}
...
}
- if(E) pr(es);
// </smpl>

Tested by compilation only.
