[PATCH v2 1/2] branch: refactor "edit_description" code path

["Rubén Justo" <rjusto@gmail.com>]

Minor refactoring to reduce the number of returns in the switch case
handling the "edit_description" option, so the calls to strbuf_release
can also be reduced.  New resources to be added also do not need to be
released in multiple places.
