rtc: mc146818-lib: fix signedness bug in mc146818_get_time()
commit 7372971c1be5b7d4fdd8ad237798bdc1d1d54162 upstream.
The mc146818_get_time() function returns zero on success or negative
a error code on failure. It needs to be type int.
Fixes: d35786b3a28d ("rtc: mc146818-lib: change return values of mc146818_get_time()")
