Alexander Motin 3079bf2e6c Restrict short block cloning requests
If we are copying only one block and it is smaller than recordsize
property, do not allow destination to grow beyond one block if it
is not there yet.  Otherwise the destination will get stuck with
that block size forever, that can be as small as 512 bytes, no
matter how big the destination grow later.
