librbd/cache/pwl: Fix dead lock issue when pwl initialization failed

when pwl initialization failed, 'AbstractWriteLog' will release itself
in callback, it hold guard lock and want to get lock to delete data,
which causes dead lock. This PR works by release image_cache outside
the callback function.
