fscache: Allow cancelled operations to be enqueued
Alter the state-check assertion in fscache_enqueue_operation() to allow
cancelled operations to be given processing time so they can be cleaned up.
Also fix a debugging statement that was requiring such operations to have
an object assigned.
Fixes: 9ae326a69004 ("CacheFiles: A cache that backs onto a mounted filesystem")
