fix(profiles): remove os.Exit to avoid oneview TF provider from responding

[FalcoSuessgott]

Terraform fails, because the oneview library simpy os.Exit, instead of returning any error, this prevents us from getting any error messages that causes that error. This PR removes that exit statement and returns proper errors instead:
