[PATCH 4.14 066/109] perf script python: Fix export-to-sqlite.py sample columns

[Greg Kroah-Hartman]

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

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

From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

commit d005efe18db0b4a123dd92ea8e77e27aee8f99fd upstream.

With the "branches" export option, not all sample columns are exported.
However the unwanted columns are not at the end of the tuple, as assumed
by the code. Fix by taking the first 15 and last 3 values, instead of
the first 18.
