[PATCH i-g-t] tests/amdgpu/amd_replay: Add some page flips before test start

[Tom Chung]

[Why]
New panel replay driver behavior skip some atomic commits before
enable the panel replay.

[How]
Add some page flips before test to let the panel replay can be
enabled first.
(This change can be backward compatible with old driver)
