Happens every time I try to remove that inode (directory). xfs_repair
ends with a fatal error:

Phase 6 - check inode connectivity...
       - resetting contents of realtime bitmap and summary inodes
       - ensuring existence of lost+found directory
       - traversing filesystem starting at / ...

fatal error -- can't read block 16777216 for directory inode 1507133580

I'm sorry, the patch doesn't change anything. It never makes it though
the xfs_repair due to the above error. If there's any information I
can get for you please let me know.

I'm not sure if it changes anything, but here's the message after the patch:
