AFS: Fix cache manager service handlers

Fix the cache manager RPC service handlers.  The afs_send_empty_reply() and
afs_send_simple_reply() functions:

 (a) Kill the call and free up the buffers associated with it if they fail.

 (b) Return with call intact if it they succeed.

However, none of the callers actually check the result or clean up if
successful - and may use the now non-existent data if it fails.

This was detected by Dan Carpenter using a static checker:

	The patch 08e0e7c82eea: "[AF_RXRPC]: Make the in-kernel AFS
	filesystem use AF_RXRPC." from Apr 26, 2007, leads to the following
	static checker warning:
	"fs/afs/cmservice.c:155 SRXAFSCB_CallBack()
		 warn: 'call' was already freed."
