Subject: clocksource/drivers/tango-xtal: Fix boot hang due to incorrect test

From: Daniel Lezcano <daniel.lezcano@linaro.org>

commit 16eeed7e5558a3dcf30f75526a896b2632f299f9 upstream.

Commit 0881841f7e78 introduced a regression by inverting a test check
after calling clocksource_mmio_init(). That results on the system to
hang at boot time.

Fix it by inverting the test again.

Fixes: 0881841f7e78 ("Replace code by clocksource_mmio_init")
