gpu: nvgpu: fix invalid TSG pointer
In gr_gp10b_set_cilp_preempt_pending() we already extract TSG pointer
by calling tsg_gk20a_from_ch() which safely returns correct TSG or
NULL in error case
But before calling g->ops.fifo.post_event_id() we again extract TSG
by directly accessing g->fifo.tsg array, and this could result in
getting invalid TSG pointer
Fix this by removing direct TSG extraction through g->fifo.tsg
