[PATCH i-g-t, v2 1/7] tests/intel/kms_big_fb: NVL supports horizontal flip with linear surfaces

[Swati Sharma <swati2.sharma@intel.com>]

From: Sai Teja Pottumuttu <sai.teja.pottumuttu@intel.com>

Starting NVL (display version 35), horizontal flip is supported with
linear surfaces, thus don't skip that case.
