[Click] Build fix for etherswitch.cc [PATCH ATTACHED]

[Michael Gellman]

On compiling the latest CVS version of Click on Fedora Core 2, I
received the following error:

In file included from ../include/click/straccum.hh:210,
                 from ../include/click/straccum.hh:248,
                 from ../elements/etherswitch/etherswitch.cc:210:
../include/click/bighashmap.hh: In instantiation of `HashMap<EtherAddress,
EtherSwitch::AddrInfo>::Elt':
../include/click/bighashmap.hh:112:   instantiated from `const K&
_HashMap_const_iterator<K, V>::key() const [with K = EtherAddress, V =
EtherSwitch::AddrInfo]'
../include/click/straccum.hh:207:   instantiated from here
../include/click/bighashmap.hh:82: error: base `HashMap<EtherAddress,
   EtherSwitch::AddrInfo>::Pair' with only non-default constructor in class
   without a constructor

I believe the attached patch, which adds a default constructor to the
AddrInfo struct, corrects the error.
