drm/radeon/kms/r100: fix bug in CS parser
The first dword of PACKET3_3D_DRAW_IMMD maps to
SE_VTX_FMT so the vertex size is part of the draw
packet.
This patch fixes a possible case where you have a
command buffer that does not contain SE_VTX_FMT
register write, but does contain PACKET3_3D_DRAW_IMMD.
