Henrik RydgårdandClaude Opus 5.5 9372d4b490 sceIo: Validate PGD block sizes and dir listing state 
The PGD block size comes from the file header (or a savestate), and is
used to size the block buffer and as a divisor and mask, so require a sane
power of two. On load, force the next read to fill the buffer, which isn't
saved. sceIoDread only checks the listing index against the end.
