[thin_repair] fix regression in thin_repair

Browse Source 
When opening the corrupted metadata we don't need to touch the space
maps.  This used to be achieved by pretending we were opening a
metadata snap at block 0 (superblock location).  But got changed in
the recent rationalisation of the metadata constructors.

This patch introduces a bool to the metadata OPEN constructor that
says whether the space maps are needed or not.
