The xe_sysfs_timeslice_duration, xe_sysfs_preempt_timeout, and
xe_sysfs_scheduler tests do not correctly restore modified sysfs params on
test failure.
Additionally, xe_sysfs_timeslice_duration modifies but does not restore
preempt_timeout_us.
Finally, while xe_sysfs_scheduler does attempt to restore all modified
sysfs params at the end of the tests, no guarantee is made that the
restorations are successful.
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)

v7: Also fix xe_sysfs_scheduler

v8: Update igt_sysfs_get_engine_list to no longer require reporting
    size (Kamil)
    Remove assertion for some sysfs writes to succeed, as we only
    require that the end result is correct.
