commit 09796413394c5490c4adfc5cded5d4344af6af17

tests/kms_cursor_legacy: Fix assertion failure due to vblank mismatch
For the !modeset case, after a pageflip is performed on both crtc's,
vblank counter is advanced by 1 when compared to its original value.
For the modeset case, when pageflips and modesets are interleaved,
vblank counter does not always advance by 1 as nonblocking modeset
could fail, in which case we do not need vblank_matches.
v2: Remove the assert statement instead of changing the condition
