tracing/filters: use ring_buffer_discard_commit for discarded events
The ring_buffer_discard_commit makes better usage of the ring_buffer
when an event has been discarded. It tries to remove it completely if
possible.
This patch converts the trace event filtering to use
ring_buffer_discard_commit instead of the ring_buffer_event_discard.
