octeontx2-af: Disable SMQ sticky mode to avoid NIX PSE deadlock

commit 05063a9d6260165c5c510bcb7d8c70bdb87e3da0 from
git@git.assembla.com:cavium/WindRiver.linux.git

NIX PSE may deadlock when they are any sticky to non-sticky
transmission. Hence disable sticky mode.
Set condition clock to avoid droping of credits.
