[PATCH v2] rtc: max8997: Fix the returned value in case of error in 'max8997_rtc_read_alarm()'

[Christophe JAILLET]

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.

v2: re-word changelog and remove Fixes tag.
