Fixes for 5.10-rc3:

- Fix an uninitialized struct problem.
- Fix an iomap problem zeroing unwritten EOF blocks.
- Fix some clumsy error handling when writeback fails on
  blocksize < pagesize filesystems.
- Fix a retry loop not resetting loop variables properly.
- Fix scrub flagging rtinherit inodes on a non-rt fs, since the kernel
  actually does permit that combination.
