Steven Rostedt 74c0c6483b tracing: Have syscall trace events use trace_event_buffer_lock_reserve() ...

commit 3e2a56e6f6 upstream.

Currently, the syscall trace events call trace_buffer_lock_reserve()
directly, which means that it misses out on some of the filtering
optimizations provided by the helper function
trace_event_buffer_lock_reserve(). Have the syscall trace events call that
instead, as it was missed when adding the update to use the temp buffer
when filtering.
