Subject[for-next][PATCH 2/2] tracing: Fix clear of RECORDED_TGID flag when disabling trace event
From: Chunyu Hu <chuhu@redhat.com>

When disabling one trace event, the RECORDED_TGID flag in the event
file is not correctly cleared. It's clearing RECORDED_CMD flag when
it should clear RECORDED_TGID flag.
