[igt-dev] [PATCH i-g-t 2/3] tests/kms_available_modes_crc: Initialize fb struct

[Dhinakaran Pandiyan]

The test does not initialize data->fb, initializing stride and offset is
necessary to fill NV12 planes correctly. We should ideally be using
library functions in place handrolled code in this test, but let's start
with fixing the failures.
