[PATCH i-g-t] test/kms_properties.c: fix connector-properties

[Bhawanpreet Lakha]

    The test doesn't consider immutable properties

    Legacy Test: The test trys to set the property, but if the property
                 is immutable the test fails.
                 Added conditions to check if the property is immutable.

    Atomic Test: The immutable properties are added and fails on commit.
                 Added condition to skip 'add property' if the property
                 is immutable. This insures that the commit will not fail.

                 Skipping the add property is the only way, because otherwise
                 the the actual commit will always fail if there is atleast
                 one immutable property.
