asm-generic: Add missing brackets for io_stop_wc macro 

After using io_stop_wc(), drivers reports following compile error when
compiled on X86.

  drivers/net/ethernet/hisilicon/hns3/hns3_enet.c: In function ‘hns3_tx_push_bd’:
  drivers/net/ethernet/hisilicon/hns3/hns3_enet.c:2058:12: error: expected ‘;’ before ‘(’ token
    io_stop_wc();
              ^
It is because I missed to add the brackets after io_stop_wc macro. So
let's add the missing brackets.

Fixes: d5624bb29f ("asm-generic: introduce io_stop_wc() and add implementation for ARM64")
