[PATCH 10/10] submodule deinit: complain when given a file instead of a submodule

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.
