Subject[PATCH] gpu: drm: nouveau: Use list_for_each_entry_from_reverse
It's better to use "list_for_each_entry_from_reverse" for iterating list
than "for loop" as it makes the code more clear to read.
This patch replace "for loop" with "list_for_each_entry_from_reverse"
and remove "cstate" variable as it is redundant in the code.
