MT#60476 sdp_version_replace: don't check src_orig ptr

Already checked before in sdp_version_check.

Fixes defect:

/daemon/sdp.c: 2936 in sdp_version_replace()
2930                            /* update string unconditionally to keep position tracking intact */
2931                            chopper_replace(chop, &origin->version_str, &origin->version_output_pos, version_str, version_len);
2932                    }
2933            }
2934            /* for sdp_create */
2935            else {
>>>     CID 1598877:  Null pointer dereferences  (REVERSE_INULL)
>>>     Null-checking "src_orig" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
2936                    if (!other_orig || !src_orig)
2937                            return;

2940                    /* is our new value longer? */
2941                    if (version_len > other_orig->version_str.len) {
