Erik Kline 725e8f6856 Always close file descriptors
Every error thrown leaked a netlink NETFILTER socket.

Test: as follows
    - built, flashed, booted
    - runtest frameworks-net passes
    - enabled tethering and tried to cause conntrack updates to sessions
      that had expired (which causes ErrnoExceptions to be thrown)
      while monitoring lsof for system_server's NETFILTER sockets
