Thomas Fleury 45fa0441f7 gpu: nvgpu: allocate only active runlists ...

Currently a fifo_runlist_info_gk20a structure is allocated and
initialized for each possible runlist. But only a few runlists
are actually used.

Skip allocation and initialization of inactive runlists.
Active runlists info is stored in the active_runlist_info array.
If a runlist is active, then runlist_info[runlist_id] points to
one entry in active_runlist_info. Otherwise, runlist_info[runlist_id]
is NULL.

Operations that used to walk through all runlists are modified to
walk though active runlists only.
