submodule: remove fetch.recursesubmodules from submodule-config parsing

bmwill · gitster · commit 8fa2915971e5 · 2017-08-02T14:26:46.000-07:00
Remove the 'fetch.recursesubmodules' configuration option from the
general submodule-config parsing and instead rely on using
'config_from_gitmodules()' in order to maintain backwards compatibility
with this config being placed in the '.gitmodules' file.
