ASTERISK-24983: Prevent deadlock between hanup and sending lagrq/ping

channels/chan_iax.c: Prevent the deadlock between iax2_hangup and send_lagrq/
send_ping. This deadlock happens because scheduled task send_lagrq(or send_ping)
start execution after call hangup procedure started but before deleting the
tasks the scheduler. The solution is to prevent lagrq (and ping) from acquiring
the mutex if call disappear or hangup in process. This commit cleans up the
procedure of sending LAGRQ and PING.

main/sched.c: Add warning message if scheduler is stuck while deleting and
executing task.
