nilfs2: fix kernel oops in error case of nilfs_ioctl_move_blocks
This fixes a kernel oops reported by Markus Trippelsdorf in the email
titled "[NILFS users] kernel Oops while running nilfs_cleanerd".
The oops was caused by a bug of error path in
nilfs_ioctl_move_blocks() function, which was inlined in
nilfs_ioctl_clean_segments().
nilfs_ioctl_move_blocks checks duplication of blocks which will be
moved in garbage collection. But, the check should have be done
within nilfs_ioctl_move_inode_block() to prevent list corruption among
buffers storing the target blocks.
To fix the kernel oops, this moves forward the duplication check
before the list insertion.
I also tested this for stable trees [2.6.30, 2.6.31].
