Subject: [PATCH 3/3] perf tools: Move symbol annotation to resort

Currently the we make annotation for ipc column during the
entry display, already outside the progress bar scope, so
it appears like perf report is stuck.

Moving the annotation retrieval to the resort phase, so all
the data are ready for display.
