rtc: max77686: Fix the returned value in case of error in 'max77686_rtc_read_time()'

Browse Source 
[ Upstream commit b28cc6cec3d814f5184cbebb2d1f987e769f534a ]

In case of error, we return 0.
This is spurious and not consistent with the other functions of the driver.
Commit e115a2bf1426 has modified more than what is said in the commit
message. Reverse part of it znd return an error when needed, as it was
previously.

Fixes: e115a2bf1426 ("rtc: max77686: stop validating rtc_time in .read_time")
