On unwind after failed block allocation in ffs_balloc_ufs{1,2}, assert
that recorded allocated blocks numbers match the physical block
numbers of dandling buffers which are released.

When finally freeing the blocks during unwind, assert that dandling
buffers where not re-allocated.  They shouldn't, because the vnode lock
is owned exclusive.
