uart: Change to call uart flush with void type conversion

In commit e14fc739d7de ("uart: Add nonblocking IO and assorted functions")
peripheral_uart_flush function's return type was changed void to int
And, other functions using it were changed to call it with (void) type coversion
because previous code didn't check the return of flush function.
But in close function, it was ommited so add it.
