it might not exists when a cache disk device is removed and
further cache device might be active.
Also handle the case where cache set might not be registered
and the status should just believe what the super block
says and not mark the disk as missing.
This part of code needs optimization but that is a separate
change.

Don't say that the device is missing unless it is still showing
"active" state.

Cross reference the superblock with the highest sequence number
to sysfs. If there is a device shown still active in the superblock,
mark it as 'missing'.

Previously we were reading old superblocks stuck in the cache.
Pass in O_DIRECT when opening the device. This requires that
the dest buffer be memaligned.
If we are unable to read the entire superblock then increase
the buffer and try again.
Also since we now have to alloc the sb, make sure it is freed
everywhere in bcacheadm.
