[PATCH 06/10] perf header: Set header version correctly

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Namhyung Kim <namhyung@kernel.org>

When check_magic_endian() is called, it checks the magic number in the
perf data file to determine version and endianness.  But if it uses a
same endian the verison number wasn't updated and makes confusion.
