squashfs: fix incorrect argument to sizeof in kmalloc_array call

Browse source 
The sizeof(void *) is the incorrect argument in the kmalloc_array call, it
best to fix this by using sizeof(*cache_folios) instead.

Fortunately the sizes of void* and folio* happen to be the same, so this
has not shown up as a run time issue.
