Subject: [PATCH net] cxgb4: fix thermal zone build error

with CONFIG_THERMAL=m and cxgb4 as built-in build fails, and
'commit e70a57fa59bb ("cxgb4: fix thermal configuration dependencies")'
tires to fix it but when cxgb4i is made built-in build fails again,
use IS_REACHABLE instead of IS_ENABLED to fix the issue.
