QSocks5SocketEngine: Remove too optimistic check for UDP proxy setup

The engine used to send a UDP datagram to the local address to check
the proxy setup, but the check fails in case of the proxy hosted in
WAN and the local address hidden behind a NAT. In other words the
check fails because a public proxy hosted somewhere in internet has
no access to local addresses such as 192.168.1.2.

Remove the check to fix the issue; we still have other means to
detect network errors.
