gpu: nvgpu: fix ppc broadcast address split

Browse Source 
In gr_gk20a_split_ppc_broadcast_addr() we convert a PPC broadcast address to
its corresponding unicast address list
But we consider gr.pe_count_per_gpc instead of actual number of PPCs and that
leads to generating incorrect list of addresses

Fix this by using gr.gpc_ppc_count[gpc_num] which gives correct number of
PPC count
