    x86: fix disassembler build after 1a3b4f90bc5f
    
    In commit 1a3b4f90bc5f ("x86: convert two pointers to (indexing)
    integers") I neglected the fact that compilers may warn about comparing
    ptrdiff_t (signed long) with size_t (unsigned long) values. Since just
    before we've checked that the value is positive, simply add a cast
    (despite my dislike for casts).
