    [CIFS] fix saving of resume key before CIFSFindNext

    We recently fixed the cifs readdir code so that it saves the resume key
    before calling CIFSFindNext. Unfortunately, this assumes that we have
    just done a CIFSFindFirst (or FindNext) and have resume info to save.
    This isn't necessarily the case. Fix the code to save resume info if we
    had to reinitiate the search, and after a FindNext.

    This fixes connectathon basic test6 against NetApp filers.

    [CIFS] make sure we have the right resume info before calling
CIFSFindNext

    When we do a seekdir() or equivalent, we usually end up doing a
    FindFirst call and then call FindNext until we get to the offset that we
    want. The problem is that when we call FindNext, the code usually
    doesn't have the proper info (mostly, the filename of the entry from the
    last search) to resume the search.

    Add a "last_entry" field to the cifs_search_info that points to the last
    entry in the search. We calculate this pointer by using the
    LastNameOffset field from the search parms that are returned. We then
    use that info to do a cifs_save_resume_key before we call CIFSFindNext.

    This patch allows CIFS to reliably pass the "telldir" connectathon
test.
