mds: cancel fragmenting dirfrags when cluster is degraded

when cluster is degraded, acquiring locking can take long time.
It is not good to keep dirfrags in frozen state for a long time.

To allow cancelling fragment operation at any time, this commit
also reorganizes the codes that freeze/fetch dirfrags.
