ftrace: Fix uninitialized variable in match_records()
commit 2e028c4fe12907f226b8221815f16c2486ad3aa7 upstream.
My static checker complains that if "func" is NULL then "clear_filter"
is uninitialized. This seems like it could be true, although it's
possible something subtle is happening that I haven't seen.
kernel/trace/ftrace.c:3844 match_records()
error: uninitialized symbol 'clear_filter'.
