[PATCH v3] submodule-config: fix reading submodule.fetchJobs

["Saagar Jha via GitGitGadget" <gitgitgadget@gmail.com>]

From: Saagar Jha <saagar@saagarjha.com>

update_clone_config_from_gitmodules() passes &max_jobs to
config_from_gitmodules(), but max_jobs is already a pointer. This causes
the config value to be written to the wrong address and get dropped.

Pass max_jobs directly.

     -    The old code accidentally passed &max_jobs rather than max_jobs into
     -    config_from_gitmodules, which caused the setting to be written to the
     -    wrong place and dropped.
