[PATCHv12 07/10] send-pack: rename ref_update_to_be_sent to check_to_send_update

[Stefan Beller <sbeller@xxxxxxxxxx>]

This renames ref_update_to_be_sent to check_to_send_update and inverts
the meaning of the return value. 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 CHECK_REF_STATUS_REJECTED
case.
