Bug description:
  [SRU Justification][YAKKETY]

  fwts segfaults when running a fwts method test because of a double
  unlock on a pthread mutex.

  [FIX]
  Upstream commit https://lists.ubuntu.com/archives/fwts-devel/2016-October/008679.html - don't do double unlocking

  [TEST CASE]
  run fwts method - on the firmware and we get a double unlock on method invocation accounting and a segfault occurs. With the fix there is no segfault.

  [REGRESSION POTENTIAL]
  Minimal impact; this affects method invocation accounting and just the fwts method execution.  The fix only changes the accounting and will not affect other fwts test components.

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

  
  Test 46 of 192: Test _OFF (Set resource off).
  PASSED: Test 46, \_SB_.PCI0.PEG0.PEGP._OFF returned no values as expected.
  Caught SIGNAL 11 (Segmentation fault), aborting.
