bitbake: fetch2/gitsm: Fix when repository change submodules

This fix a problem when checking out a commit that changes the submodules
previously checkout.

Example:
Recipe uses branch A and then it updates to use branch B, but branch B has
different submodules dependencies then what branch A previously had.
