Subject: tests/tcg: fix unused variable in linux-test
X-Git-Tag: pull-xen-20230306~86^2~2

tests/tcg: fix unused variable in linux-test

The latest hexagon compiler picks up that we never consume wcount.
Given the name of the #define that rcount checks against is WCOUNT_MAX
I figured the check just got missed.
