submodule init: fail gracefully with a missing .gitmodules file
When there is no .gitmodules file availabe to initialize a submodule
from, `submodule_from_path` just returns NULL. We need to check for
that and abort gracefully. When `submodule init` was implemented in shell,
a missing .gitmodules file would result in an error message
No url found for submodule path '%s' in .gitmodules
Replicate that error message for now.
When the .gitmodules file is missing we can probably fail even earlier
for all of the submodules with an improved error message.
