ceph: check availability of mds cluster on mount after wait timeout
[ Upstream commit 97820058fb2831a4b203981fa2566ceaaa396103 ]
If all the MDS daemons are down for some reason, then the first mount
attempt will fail with EIO after the mount request times out. A mount
attempt will also fail with EIO if all of the MDS's are laggy.
This patch changes the code to return -EHOSTUNREACH in these situations
and adds a pr_info error message to help the admin determine the cause.
