[CUDA] Fix arguments after removing unused private variable

Summary:
A previous patch removed the use of the `OK` private variable in CUDA
which resulted in usused variable warnings. this was fixed in
f886f7e but did not change the
constructor to accurately represent its removal. This patch removes it
from the interface entirely.
