Staging: lustre: Unnecessory else and braces are removed

This patch fixes following checkpatch.pl warning using coccinelle:

WARNING: else is not generally useful after a break or return

Semantic patch used for this is as follows:

@rule1@
expression e1;
@@

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

@rule2@
expression e2;
statement s1;
@@

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