sound: oss: Remove typedefs wanc_info and wavnc_port_info

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

A simplified version of the Coccinelle semantic patch that finds the case is:

@tn@
identifier i;
type td;
@@

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

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

-td
+ struct i
