Revert "NVIDIA: SAUCE: WAR: tee: optee: Add timeout in wq_sleep()"

This reverts commit db18e862162e778023211f7a54ec265af15f6fd1. Upstream
commit 14ca6401d870 ("optee: add timeout value to optee_notif_wait() to
support timeout") added a timeout value to optee_notif_wait() and so we
can drop this change in favour of the upstream commit.
