dlls/iphlpapi/iphlpapi_main.c -- initialise field in pAdapterInfo

[Guido Barzini]

 The pAdapterInfo->AddressLength field needs to be set to the available
space before getInterfacePhysicalByIndex is called. This used to be done, but 
the initialisation was lost during some recent changes, making retrieval of 
the physical address fail (see http://bugs.winehq.org/show_bug.cgi?id=10657).
This one-line patch restores the previous behaviour.
