[PATCH 05/18] perf tools: Fix typo on hist__entry_add_pair

[Namhyung Kim <namhyung@kernel.org>]

From: Namhyung Kim <namhyung.kim@lge.com>

Fix a misplaced underscore.  In this case, 'hist_entry' is the name of
data structure and we usually put double underscores between data
structure and actual function name.
