drm: for minimum buffer size to be greater than 0HEADmaster

The drm driver tells us the minimum dimensions it supports
for buffer objects.  We use this minimum for creating a
small temporary 32-bit buffer to test if 32-bit buffers
are supported.

Unfortunately, some drivers neglect to fill in
min_width/min_height and then we try to allocate a buffer
with 0 sized dimensions.

This commit checks for min_width/min_height being 0, and then
bumps them to 1.

Minor changes to initial patch by Ray Strode.
