[PATCH] clocksource/drivers/tango-xtal: Fix boot hang due to incorrect test

[Daniel Lezcano]

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")
