FIXES 6002

The appended patch resets afs_globalVFS to NULL if /afs cannot be mounted,
eg., if no cell server is accessible.

There are two advantages:

 - it is possible to do "afsd -shutdown" to terminate all daemons
 - more importantly, if /afs cannot be mounted, the linux kernel will
   probably free the superblock, ie the memory pointed to afs_globalVFS.
