[Xf86-video-armsoc] [PATCH 1/1] Clarify assumptions on window front buffer pixmaps

[armsoc-bugs at arm.com]

From: Raymond Smith <raymond.smith at arm.com>

We assume that a window's front buffer pixmap won't be reallocated
from beneath us. This commit updates a comment to reflect this
assumption.
