compat_ioctl: Remove unused local typedef

gcc 4.8 always warns

fs/compat_ioctl.c: In function 'serial_struct_ioctl':
fs/compat_ioctl.c:609:38: warning: typedef 'SS' locally defined but not used [-Wunused-local-typedefs]
         typedef struct serial_struct SS;

Indeed that typedef is unused, so just remove it.
