[igt-dev] [i-g-t 1/2] tests/kms_cursor_legacy: Fix CI tiemout issues

[Bhanuprakash Modem]

After introducing the dynamic subtests, tests are getting timedout
on CI. This patch will partially reverts dynamic subtests to avoid
such timeouts.

Fixes: c02f0d48c (tests/kms_cursor_legacy: Convert tests to dynamic)
