nilfs2: simplify handling of active state of segments fix
This fixes a bug of ("nilfs2: simplify handling of active state of
segments") patch. The patch did not take account that a base index is
increased in nilfs_sufile_get_suinfo() function if requested entries
go across block boundary on sufile.
Due to this bug, the active flag sometimes appears on wrong segments
and has induced malfunction of garbage collection.
