rtc: max8997: Fix the returned value in case of error in 'max8997_rtc_read_alarm()'

BugLink: https://bugs.launchpad.net/bugs/1857158
[ Upstream commit 41ef3878203cd9218d92eaa07df4b85a2cb128fb ]

In case of error, we return 0.
This is spurious and not consistent with the other functions of the driver.
Propagate the error code instead.
