[PATCH 15/24] entry.c: use the right index instead of the_index

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

checkout-index.c needs update because if checkout->istate is NULL,
ie_match_stat() will crash. Previously this is ie_match_stat(&the_index, ..)
so it will not crash, but it is not technically correct either.
