src/process.c Correctly convert AF_INET6 addresses

* src/process.c (conv_lisp_to_sockaddr): AF_INET6 addresses are
converted to a list of 16 bit quantities by
conv_sockaddr_to_lisp(). conv_lisp_to_sockaddr() should follow the
same scheme rather than expecting a (longer) list of 8 bit
quantities.

Backport:
