gpu: nvgpu: unit: update dummy pes_tpc_mask for better coverage

Browse Source 
Update gr_test_config_get_pes_tpc_mask() to return 0x2F when called
for third time.

There are 2 PES in a GPC. So essentially we want to cover below two
cases
1. pes_tpc_count[pes0][gpc0] > pes_tpc_count[pes1][gpc0]
2. pes_tpc_count[pes0][gpc0] < pes_tpc_count[pes1][gpc0]

Also, run gr_test_diff_gpc_skip_mask() before gr_test_diff_pes_tpc_mask()
so that gpc_skip_mask calculation can generate above two cases first.
