[PATCH] afs_proc_cleanup()

[B N Poornima]

Hi,
This is regarding a bug in the 'kafs' module. Whenever the kafs module
is unloaded, it produces the following stack trace. 
********************************************************************
kAFS: Red Hat AFS client v0.1 unregistering.
BUG: at fs/proc/generic.c:732 remove_proc_entry()
 [<c0195380>] remove_proc_entry+0x11b/0x175
 [<c013b52e>] sys_delete_module+0x1a5/0x1cf
 [<c0158bc2>] remove_vma+0x36/0x3b

 [<c0103da0>] syscall_call+0x7/0xb
 [<c02a0033>] nf_ip_checksum+0xd4/0xe1
 =======================
***************************************************************
The problem is reproducible on the latest rc kernel - 2.6.20-rc5. The
cause of the problem being kafs driver trying to free the /proc/fs/afs
directory which is not empty. 
I'm attaching the patch which solves the problem, for review.
