ut/blob: issue to consecutive md syncs

Browse Source 
Expands blob_simultaneous_operations to cover case
when second md sync is perfomed without waiting for the first
one to complete.

The blob state is forced in UT, but in normal usage could be
changed by modifying xattr, allocating thin clusters or other.
