test: fix invalid common.mustSucceed() usage

By its own nature, the function returned by `common.mustSucceed()`
cannot be used as a listener for `'error'` events.

Write errors like `read ECONNRESET` or `write EPIPE`, should be ignored
because the socket might be closed by the other peer while the request
is sent.
