[Gerrit Code Review]

The following commit has been merged in the openafs-stable-1_4_x branch:
commit 8644f90a75281c8f678e2c3b93531857b9f3fa1f
Author: Andrew Deason <adeason@sinenomine.net>

    Do not trust FetchData length from fileservers
    
    Currently the Unix CM implicitly trusts that the length from a FetchData
    request from a fileserver will always be less than the requested length.
    If the fileserver sends more data than requested, we can use up more
    cache space than we intended, possibly exceeding the cacheinfo cache
    limits.
    
    Add a check for this, and return EIO to the caller if the fileserver
    responds with too much data.
