[igt-dev] [PATCH i-g-t v1 3/3] tests/kms_rotation_crc: Use igt_get_assigned_primary to get the primary plane

[Jessica Zhang]

Currently, test_plane_rotation calls igt_output_get_plane_type to get
the plane with the corresponding type then calls drmModePageFlip when
the plane is a primary plane.

This will cause issues in cases where there are multiple primary planes
as the primary plane taken from igt_output_get_plane_type might not be
the primary plane being assigned to the pipe by the driver.

To fix this, let's use igt_get_assigned_primary to get the assigned
primary plane of the driver.
