<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">If transmit_refer is called when p->refer is already allocated, it will leak the previous allocation. I checked for all occurrences of sip_refer_alloc, found that transmit_refer was the only caller that didn't check p->refer first. This change moves the check for !p->refer to sip_refer_alloc.
I made transmit_refer destroy any previous p->refer so it will have a clean structure after reallocation like it does currently. Unsure if it's needed, but the little bit of extra processing is worth keeping this fix low risk.
The change is slightly different in 12+, as p->refer->refer_call only exists in 11.</pre>
