Michael Ellerman 2bf66e66d2 selftests/powerpc: Fix argument order to timer_sub() 
Commit c814bf9589 ("powerpc/selftests: Use timersub() for
gettimeofday()"), got the order of arguments to timersub() wrong,
leading to a negative time delta being reported, eg:

  test: gettimeofday
  tags: git_version:v6.12-rc5-409-gdddf291c3030
  time = -3.297781
  success: gettimeofday

The correct order is minuend, subtrahend, which in this case is end,
start. Which gives:

  test: gettimeofday
  tags: git_version:v6.12-rc5-409-gdddf291c3030-dirty
  time = 3.300650
  success: gettimeofday

Fixes: c814bf9589 ("powerpc/selftests: Use timersub() for gettimeofday()")
