rtc: ds1307: check for failed memory allocation on wdt
Currently a failed memory allocation will lead to a null pointer
dereference on point wdt. Fix this by checking for a failed
allocation and just returning.
Addresses-Coverity: ("Dereference null return")
Fixes: fd90d48db037 ("rtc: ds1307: add support for watchdog timer on ds1388")
