Re: [libvirt] [PATCHv2 1/2] util: set missing data length in virSocketAddrPrefixToNetmask()

This fixes a bug that has been present since the original version of the function was pushed in commit 1ab80f3 on Nov. 26 2010 (by me). The virSocketAddr::len was not being set. Apparently until now we were always calling virSocketAddrPrefixToNetmask() with a virSocketAddr object that was already (coincidentally) initialized for the proper address family, but the bug became apparent when trying to use it to fill in an otherwise uninitialized object.
