Revert "submodules: fix of regression on fetching of non-init subsub-repo" 

This reverts commit 1b7ac4e6d4d490b224f5206af7418ed74e490608; in
<CAN0XMOLiS_8JZKF_wW70BvRRxkDHyUoa=Z3ODtB_Bd6f5Y=7JQ@mail.gmail.com>,
Ralf Thielow reports that "git fetch" with submodule.recurse set can
result in a bogus and infinitely recursive fetching of the same
submodule.
