[Mesa-dev] [PATCH] radeonsi: Fix calculation of number of records in buffer resource.

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

The value was too small by 1 in some cases (non-first of several vertex
elements interleaved in a single buffer).

Fixes intermittent incorrect geometry in many apps, e.g. piglit
spec/EXT_texture_snorm/fbo-generatemipmap-formats.
