[PATCHv2 2/6] send-pack: Invert the return value of ref_update_to_be_sent

[Stefan Beller <sbeller@google.com>]

Having the return value inverted we can have different values for
the error codes. This is useful in a later patch when we want to
know if we hit the REF_STATUS_REJECT_* case.

Notes:
    New in the series. For consistency with all the other patches
    it also reads v2.
