Subject[patch 14/27] CIFS: fix saving of resume key before CIFSFindNext
2.6.27-stable review patch.  If anyone has any objections, please let us 
know.

------------------
From: Jeff Layton <sfrench@us.ibm.com>
commit a364bc0b37f14ffd66c1f982af42990a9d77fa43 upstream

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.
