dir.c: clean the entire struct in clear_exclude_list()

Make sure "el" can be reuseable again. The problem was el->alloc is not cleared and may cause segfaults next time because add_exclude() thinks el->excludes (being NULL) has enough space. Just clear the entire struct to be safe. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
