[PATCH] 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.
Commit 22652ba72453 has modified more than what is said in the commit
message and error should be propagated.

Fixes: 22652ba72453 ("rtc: stop validating rtc_time in .read_time")

Not sure that the Fixes tag is the right one.
It is related, but not 100% accurate IMHO.
