may_packing in __z_erofs_compress_one() is still bypassed when multi-threaded
compression is enabled, which is unexpected.
Furthermore, multi-threaded -Eall-fragments,ztailpacking can sometimes corrupt
images. Let's fix it.
Fixes: 882ad1c3157f ("erofs-utils: mkfs: fix `-Eall-fragments` for
multi-threaded compression")
Fixes: 10c1590c0920 ("erofs-utils: enable multi-threaded support for
`-Eall-fragments`")
