[PATCH] [submodule] Remove duplicate call to set_rev_name

[Fredrik Gustafsson <iveqy@iveqy.com>]

set_rev_name is a possible expensive operation. If a submodule has
changes in it, set_rev_name was called twice.

Solution is to move set_rev_name so it's only called once, no matter the
codepath taken.
