[PATCH 17/22] btrfs: tests: return error from all extent map test cases

[David Sterba <dsterba@xxxxxxxx>]

The way the extent map tests handle errors does not conform to the rest
of the suite, where the first failure is reported and then it stops.
Do the same now that we have the errors returned from all the functions.
