&nbsp;&nbsp;chan_sip: fixes provisional keepalive scheduled item crash<br/>
&nbsp;&nbsp;<br/>
&nbsp;&nbsp;There is a scheduler item in chan_sip that keeps sending the<br/>
&nbsp;&nbsp;last provisional message in response to an INVITE Request for<br/>
&nbsp;&nbsp;a period of time until a final response to that INVITE is<br/>
&nbsp;&nbsp;sent.&nbsp; Because of the way this scheduler item works, it requires<br/>
&nbsp;&nbsp;a reference to a sip_pvt pointer to work properly.&nbsp; The problem<br/>
&nbsp;&nbsp;with this is that it is currently possible (but rare) for the<br/>
&nbsp;&nbsp;sip_pvt to get destroyed and that scheduler item to still<br/>
&nbsp;&nbsp;exist.&nbsp; When this occurs, the scheduler event fires and attempts<br/>
&nbsp;&nbsp;to access a freed sip_pvt which causes a crash.<br/>
&nbsp;&nbsp;<br/>
&nbsp;&nbsp;(closes issue #17497)<br/>
