minix: fix error handling in minix_set_link
If minix_prepare_chunk fails, updating c/mtime and marking the
dir inode dirty is wrong, as the inode hasn't been modified. Also
propagate the error to the caller.
Note that this moves the dir_put_page call later, but that matches
other uses of this helper in the directory code.
