channels/chan_pjsip: fix deadlock in response retransmissions

The tdata containing response can be shared by both the dialog
object and the tsx object.  In order to prevent the a race condition
betweet tsx retransmission and dialog sending a response, cancel
the retransmission timer before sending a new response.
