fix allocation error

[abraidwood]

This code has the same allocation error that mine had - that "t" can be greater than the block-size. When this happens, insufficient memory is allocated

Thank your for your patch. I prefer to allocate necessary memory directly to a while loop:

      require: function(n) {
        if (l - c < n) {
          var buf2 = new bufType(l += blockSize * Math.ceil( (l - c + n ) / blockSize ));
          buf2.set(buf);
          buf = buf2;
        }
        c += n;
        return buf;
      },  

I will update my port of minilzo-decompress later.

Sometime decompressed buffer size is known, it is better to have a option to assign it ahead in your implementation.

Thanks a lot for your help.
