Log Message:
Fix error path in ip6 source address selection.
in6_selectsrc previously returned a pointer to an ipv6 address,
the pointer was NULL in case of an error and is checked later
instead of the also returned error code. When in6_selectsrc was
changed to store the address into a buffer, the error code
was still ignored, but the buffer pointer was never set to NULL.
As a result send() to an ipv6 address on a system that isn't
configured for ipv6 no longer returns the expected EADDRAVAIL
but fails later in ip6_output with EOPNOTSUPP when trying to
send from an unspecified address. The wrong error code caused
BIND to log the unexpected errors.
