From: David Howells <dhowells@redhat.com>

commit 4636cf184d6d9a92a56c2554681ea520dd4fe49a upstream.

Fix a couple of tracelines to indicate the usage count after the atomic op,
not the usage count before it to be consistent with other afs and rxrpc
trace lines.

Change the wording of the afs_call_trace_work trace ID label from "WORK" to
"QUEUE" to reflect the fact that it's queueing work, not doing work.

Fixes: 341f741f04be ("afs: Refcount the afs_call struct")
