[PATCH 7/8] perf ui tui: Register the error callbacks before initializing the widgets

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

I.e. we want to tell the user about errors found during, for instance,
the ui_browser initialization, so that a call to ui__warning() appears
as a window waiting for a key to be pressed.
