[OpenAFS] check fs consistency after suspend/resume?

Calling something like this should be simple in Linux.  For example, on 
Ubuntu you can put a sh script stub in /etc/acpi/resume.d/ that gets 
called during the resume process.  I would assume there are analogous 
options available in other distributions.

Keep in mind that after resuming you'll want to wait for networking to 
come back up and be stable before running at least some of the 
aforementioned commands ('fs checkservers' in particular).  With DHCP 
transactions, lower-level link negotiations, and some slow networking 
drivers, I've seen it take up to 30 seconds to get a stable connection.

Of course, you can ignore all of this if the Linux/Unix client is also 
power management aware like Windows.  Is it?  If not, will we see that 
in a future release?
