staging: lustre: lustre: Remove unnecessary else after return

Else is unnecessary when there is a return statement in the
corresponding if block. Coccinelle patch used:

@rule1@
expression e1;
@@

	if (e1) { ... return ...; }
-       else{
	        ...
-       }

@rule2@
expression e2;
statement s1;
@@

	if(e2) { ... return ...; }
-       else
		s1
