Jeff Layton a87c9ad956 cifs: fix actimeo=0 corner case when cifs_i->time == jiffies 
actimeo=0 is supposed to be a special case that ensures that inode
attributes are always refetched from the server instead of trusting the
cache. The cifs code however uses time_in_range() to determine whether
the attributes have timed out. In the case where cifs_i->time equals
jiffies, this leads to the cifs code not refetching the inode attributes
when it should.

Fix this by explicitly testing for actimeo=0, and handling it as a
special case.
