squashfs: more metadata hardening
commit d512584780d3e6a7cacb2f482834849453d444a1 upstream.
Anatoly reports another squashfs fuzzing issue, where the decompression
parameters themselves are in a compressed block.
This causes squashfs_read_data() to be called in order to read the
decompression options before the decompression stream having been set
up, making squashfs go sideways.
