FS#11722 - Runtime statistics data not gathered for first song played after power-on

The reason is that, depending on the thread scheduling, the tagtree_buffer_event function may attempt to access the tagcache before it is initialized.

I could reproduce this problem on my Sansa ClipV2, but not with the simulator, which had a slightly different schedule during startup.

When problem occurs, the debug logfiles shows this:

load track: /PODCASTS/foo.mp3
tc stat: not found: /PODCASTS/foo.mp3
loading tagcache to ram...
tagcache loaded into ram!
Request new track
codec >| audio Q_AUDIO_CHECK_NEW_TRACK
No tagcache index pointer found

As you can see, the tagcache is initialized after the first song is buffered. The “tc stat: not found” message is generated by tagtree_buffer_event, and the “No tagcache index pointer found” message is generated by tagtree_track_finish_event.

The attached patch fixes the problem by deferring the use of the tagcache until it has been initialized.
