thin: report proper status for thin pool

Browse Source 
After commit 158e9988768be344c0c97acdf52d1c020ab8c83e where we may
start to readlv_attr with a 'shared' ioctl call for a single lvs line
we where obtaing single status for thin pools.
However this is not properly reflecting lvm2 reality.

Correcting this by reading lv status from layered thin pool, but lv info
from non-layered (linear) mapped device which is maintained for proper
cluster locking.
