[PATCH] clocksource/drivers/timer-cadence-ttc: fix a signedness bug in probe()

[Dan Carpenter]

Make the "irq" variable signed so the error handling can work.

Fixes: e932900a3279 ("arm: zynq: Use standard timer binding")

>From static analysis.  Untested.  Presumably if probe fails the system
is unbootable so I didn't bother looking at the resource leaks.
