This also improves performance for listing submodules, because
S_ISGITLINK is both faster as match_pathspec as well as expected to
be true in fewer cases, so putting it first in the condition will speed
up the loop to compute all submodules.
As this partially reverts 84ba959bbdf0 (submodule: fix regression for
deinit without submodules, 2016-03-22), this also disallows the use
of `git submodule deinit .` to deinit all submodules, when no
submodules are present. `deinit .` continues to work on repositories,
which have at least one submodule.
