sound: oss: uart401: Remove typedef uart401_devc 

Author: Himangi Saraogi <himangi774@gmail.com>

The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedef for uart401_devc.

The following Coccinelle semantic patch detects the case.

@tn@
identifier i;
type td;
@@

-typedef
 struct i { ... }
-td
 ;

@@
type tn.td;
identifier tn.i;
@@

-td
+ struct i
