[MINOR][BUILD] Restore to previous branch instead of detached commit
The right command to get the branch name is `git rev-parse --abbrev-ref
HEAD`
instead of `git rev-parse HEAD`. The latter returns the commit hash causing
a detached branch when we checkout to it.
We are using the same script (with some modifications) in Kafka and that is
how the issue was noticed.
