[PATCH 3/4] atm: idt77252: Remove redundant error check

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

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

Tested by compilation only.
