xfs: always check the existence of a dirent's child inode

Browse source

When we're scrubbing directory entries, we always need to iget the child
inode to make sure that the inode pointer points to a valid inode.  The
original directory scrub code (commit a5c4) only set us up to do this
for ftype=1 filesystems, which is not sufficient; and then commit 4b80
made it worse by exempting the dot and dotdot entries.

Sorta-fixes: 4b80ac6445 ("xfs: scrub should mark a directory corrupt if any entries cannot be iget'd")
