cachefiles: Wait rather than BUG'ing on "Unexpected object collision"
[ Upstream commit c2412ac45a8f8f1cd582723c1a139608694d410d ]
If we meet a conflicting object that is marked FSCACHE_OBJECT_IS_LIVE in
the active object tree, we have been emitting a BUG after logging
information about it and the new object.
Instead, we should wait for the CACHEFILES_OBJECT_ACTIVE flag to be cleared
on the old object (or return an error). The ACTIVE flag should be cleared
after it has been removed from the active object tree. A timeout of 60s is
used in the wait, so we shouldn't be able to get stuck there.
Fixes: 9ae326a69004 ("CacheFiles: A cache that backs onto a mounted filesystem")
