selftests/timers: remove unused irqcount variable

johnhubbard · shuahkh · commit 4eddfafc902b · 2024-07-11T11:23:54.000-06:00
When building with clang, via:

    make LLVM=1 -C tools/testing/selftest

...clang warns about an unused irqcount variable. clang is correct: the
variable is incremented and then ignored.

Fix this by deleting the irqcount variable.
