[PATCH] watchdog: asm9260_wdt: fix error handling in asm9260_wdt_probe()

[Alexey Khoroshilov]

If devm_reset_control_get_exclusive() fails, asm9260_wdt_probe()
returns immediately. But clks has been already enabled at that point,
so it is required to disable them.

Found by Linux Driver Verification project (linuxtesting.org).
