octeontx2-af: Remove tc rule count check while getting ntuple rule count

commit 39f9370dfed3391366c58999e096709a3be7a142 from
git@git.assembla.com:cavium/WindRiver.linux.git

Return number of ntuple rules if ntuple is enabled. No need to check
for tc rule count. Because both cannot be enabled at the same time.
