4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 7a8a8fcf7b860e4b2d4edc787c844d41cad9dfcf ]

Only use the mapped IP to find inline frames, but keep using the
unmapped IP for the callchain cursor. This ensures we properly show the
unmapped IP when displaying a frame we received via the
dso__parse_addr_inlines API for a module which does not contain
sufficient debug symbols to show the srcline.

This is another follow-up to commit 19610184693c ("perf script: Show
virtual addresses instead of offsets").
