[Intel-gfx] [PATCH i-g-t 2/3] lib/igt_kms: Set new rotation property before displaying

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

This is not really tested that much apart that it doesn't break
kms_rotation_crc and it makes one new test case work.

It only serves as proof of concept to demonstrate a particular bug.
