[igt-dev] [PATCH i-g-t 2/5] xe/xe_sysfs_scheduler: Try to set sysfs scheduler with default min

[priyanka.dandamudi at intel.com]

From: Priyanka Dandamudi <priyanka.dandamudi at intel.com>

Test tries to set sysfs scheduler with default min which is beyond local min
and assert is expected to be not equal to the set one.

v2: Added code to store and restore property in test min/max.(Tejas)
