perf annotate: Make sure to call symbol__annotate2() in TUI

perf annotate: Make sure to call symbol__annotate2() in TUI

The symbol__annotate2() initializes some data structures needed by TUI.
It has a logic to prevent calling it multiple times by checking if it
has the annotated source.  But data type profiling uses a different
code (symbol__annotate) to allocate the annotated lines in advance.
So TUI missed to call symbol__annotate2() when it shows the annotation
browser.

Make symbol__annotate() reentrant and handle that situation properly.
This fixes a crash in the annotation browser started by perf report in
TUI like below.

  $ perf report -s type,sym --tui
  # and press 'a' key and then move down
