The xe_sysfs_timeslice_duration and xe_sysfs_preempt_timeout tests do
not correctly restore modified sysfs params on test failure.
Additionally, xe_sysfs_timeslice_duration modifies but does not restore
preempt_timeout_us.  Repair these issues.

v3: Fix several formatting issues (Kamil)

v4: Do not compare possibly unassigned variable (Kamil)
    Whitespace and commit name fixes (Kamil)

v5: Add new helper funciton, igt_sysfs_get_next_engine
    Fix igt_sysfs_scanf/printf usage in tests (Kamil)

v6: Replace helper function igt_sysfs_get_next_engine with new helper
    functions that return and destroy engine lists (Kamil)

Jonathan Cavitt (3):
  lib/igt_sysfs: Add engine list helpers
  tests/intel/xe_sysfs*: Restore values on test failure
  tests/intel/xe_sysfs_timeslice_duration: Restore preempt timeout
