[Mesa-dev] [PATCH libdrm] radeon: Always multiply pitch_bytes by nsamples, not by slice_pt

[Michel Dänzer]

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

slice_pt is tileb[0] / tile_split, which isn't directly related to the
pitch.

This caused pitch_bytes to be too large in some cases.

[0] Tile size in bytes
