Subject: [PATCH] perf/test: Test case 27 broken on s390 in linux-next

Commit 10269a2ca2b08c ("perf test sample-parsing: Add endian test for struct branch_flags")
broke the test case 27 (Sample parsing) on s390 on linux-next tree:

  # ./perf test -Fv 27
  27: Sample parsing
  --- start ---
  parsing failed for sample_type 0x800
  ---- end ----
  Sample parsing: FAILED!
  #

The cause of the failure is a wrong #define BS_EXPECTED_BE statement
in above commit.  Correct this define and the test case runs fine.

Output After:
  # ./perf test -Fv 27
  27: Sample parsing                                                  :
  --- start ---
  ---- end ----
  Sample parsing: Ok
  #
