libglusterfs: Coverity Issue NEGATIVE_RETURNS
Issue: Event negative_return_fn: Function "dup(handle->fd)" returns a
negative number. Event negative_returns: "dup(handle->fd)" is passed
to a parameter that cannot be negative.
With this change value of dup(handle->fd) is stored in duped_fd & if
condition checks the value of duped_fd is non-negative.
