David Howells df44f9f4f9 AFS: Fix the module init error handling 
Fix the module init error handling.  There are a bunch of goto labels for
aborting the init procedure at different points and just undoing what needs
undoing - they aren't all in the right places, however.

This can lead to an oops like the following:

	BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
	IP: [<ffffffff81042a31>] destroy_workqueue+0x17/0xc0
