Change subject: res_pjsip_session: Fix session reference leak.
......................................................................

res_pjsip_session: Fix session reference leak.

The ast_sip_dialog_get_session function returns the session
with reference count increased. This was not taken into
account and was causing sessions to remain around when they
should not be.
