watchdog: lenovo_se30_wdt: Fix possible devm_ioremap() NULL pointer dereference in lenovo_se30_wdt_probe()
devm_ioremap() returns NULL on error. Currently, lenovo_se30_wdt_probe()
does not check for this case, which results in a NULL pointer
dereference.
Add NULL check after devm_ioremap() to prevent this issue.
