a37b06d589 Squashfs: fix breakage when page size > metadata block size 
Squashfs is broken on any system where the page size is larger than
the metadata size (8192).  This is easily fixed by ensuring cache->pages
is always > 0.

118e1ef6fa Squashfs: Fix oops when reading fsfuzzer corrupted filesystems 
This fixes a code regression caused by the recent mainlining changes.
The recent code changes call zlib_inflate repeatedly, decompressing into
separate 4K buffers, this code didn't check for the possibility that
zlib_inflate might ask for too many buffers when decompressing corrupted
data.
