[igt-dev] [PATCH 1/2] lib/intel_memory_region: Remove function which returns batch size in regions

[Jeevan B <jeevan.b@intel.com>]

From: Zbigniew Kempczyński <zbigniew.kempczynski@intel.com>

Function gem_get_batch_size() is confusing as it might return different
size thus deceiving reader of object real size created in different
memory regions.

Let's remove it and enforce igt user to be aware that kernel may alter
size where it is necessary.

v2: reword commit message (Kamil)
