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. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
