Commit 10269a2ca2b08cbd ("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
  #
