sunlimingandGreg Kroah-Hartman 5aea2ac374 tracing/user_events: Fix incorrect return value for writing operation when events are disabled ...

commit f6d026eea3 upstream.

The writing operation return the count of writes regardless of whether events
are enabled or disabled. Switch it to return -EBADF to indicates that the event
is disabled.
