tracing: Do not synchronize freeing of trigger filter on boot up
If a trigger filter on the kernel command line fails to apply (due to
syntax error), it will be freed. The freeing will call
tracepoint_synchronize_unregister(), but this is not needed during early
boot up, and will even trigger a lockdep splat.
Avoid calling the synchronization function when system_state is
SYSTEM_BOOTING.
