ceph: fix flush_dirty_caps race with caps migration
The flush_dirty_caps() used to loop over the first entry of the cap_dirty
dirty list on the assumption that after calling ceph_check_caps() it would
be removed from the list. This isn't true for caps that are being
migrated between MDSs, where we've received the EXPORT but not the IMPORT.
Instead, do a safe list iteration, and pin the next inode on the list via
the CEPH_I_NOFLUSH flag.
