ceph: add imported caps when handling cap export message
Version 3 cap export message includes information about the imported
caps. It allows us to add the imported caps if the corresponding cap
import message still hasn't been received.
This allow us to handle situation that the importer MDS crashes and
the cap import message is missing.
