[igt-dev] [i-g-t] tests/kms_atomic_transition: Reduce the execution time on simulation

[Bhanuprakash Modem]

Due to the more number of iterations, "modest-transition" tests are
getting timed out on pre-si CI. Reducing the number of iterations to
half can save a lot of execution time.

This patch will also do some cleanup before exiting the subtest.
