[igt-dev] [PATCH i-g-t v1] tests/kms_cursor_crc: Wait extra vblank

[Jessica Zhang]

Wait an extra vblank for legacy cursor ioctl to finish.

Extra vblank wait is needed for both HW and SW test as the legacy cursor
ioctl is called in both cases.

Based on Rob's patch [1] and, similarly, fixes flaky results on MSM.
