[PATCH v2] travis: Correct error checking when building boards

[Simon Glass]

At present if buildman reports an error, the travis build still succeeds.

This is because the travis script does not stop when it sees errors; nor
does it automatically return the exit code. Also the current error
checking never triggers since 'ret' is not set.

Fix this by setting 'ret' correctly.
