[77/91] drm/radeon/kms: fix GTT/VRAM overlapping test

[Greg KH]

2.6.34-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Jerome Glisse <jglisse@xxxxxxxxxx>

commit 2cbeb4efc2b9739fe6019b613ae658bd2119a3eb upstream.

GTT/VRAM overlapping test had a typo which leaded to not
detecting case when vram_end > gtt_end. This patch fix the
logic and should fix #16574
