There were places where use ui__warning (or even fprintf) to show
critical messages. This patch converts them to ui__error so that the
front-end code can implement appropriate behavior.

1.7.9.2.358.g22243
From: Arnaldo Carvalho de Melo <[email protected]>
When hide_src_view is true we can't use browser_disasm_line->idx, that
takes into account also non asm lines, we must use browser_disasm_line->idx_asm
instead, otherwise we may end up with an index after the number of
entries, oops, fix it.

From: Namhyung Kim <[email protected]>
The commit dc41b9b8f02db ("perf ui: Change fallback policy of
setup_browser") changed default behavior of the function but missed
setting the use_browser variable to 0 accidently. So perf report ends up
doing nothing in such cases. Fix it.
