Subject: [PATCH] ftrace: Call trace_parser_clear() properly

I found a weird behavior:

  # echo 'fuse:*' > set_ftrace_filter
  bash: echo: write error: Invalid argument
  # cat set_ftrace_filter
  fuse_dev_fasync
  fuse_dev_poll
  fuse_copy_do

We should call trace_parser_clear() no matter ftrace_process_regex()
returns 0 or -errno, otherwise we will actually take the unaccepted
records from ftrace_regex_release().
