[PATCH] CIFS: Fix missing entries in search results

Fix missing entries in search results when very long file names and more
than 50 (or so) of such long search entries in the directory.

FindNext could send corrupt last byte of resume name when resume key was
a few hundred bytes long file name or longer.

Fixes Samba Bug # 2932
