staging: vc04_services: Remove typedef struct

Remove typedef from struct as linux-kernel coding style tends to
avoid using typedefs

Done using following coccinelle semantic patch

@r1@
type T;

typedef struct { ... } T;

@script:python c1@
T2;
T << r1.T;
@@
if T[-2:] =="_t" or T[-2:] == "_T":
        coccinelle.T2 = T[:-2];
else:
        coccinelle.T2 = T;

print T, coccinelle.T2

@r2@
