[Nouveau] [PATCH] drm/nve4: fix size of POLY2ESETUP buffer (s/gpc_nr/tpc_total)

[Christoph Bumiller]

This fixes write faults from GPCCLIENT 5 in geometry shader tests.

For now this is just a guess from a single mmio trace, it looks
like 8 large pages are being used, i.e. one per TPC.

Can we just ask NV for the correct sizes ?
