ceph: do not confuse stale and dead (unreconnected) caps
We were using the cap_gen to track both stale caps (caps that timed out due to temporarily losing touch with the mds) and dead caps that did not reconnect after an MDS failure. Introduce a recon_gen counter to track reconnections to restarted MDSs and kill dead caps based on that instead. Rename gen to cap_gen while we're at it to make it more clear which is which.
