Increase allowed 'special_small_blocks' maximum value
There may be circumstances where it's desirable that all blocks
in a specified dataset be stored on the special device. Relax
the artificial 128K limit and allow the special_small_blocks
property to be set up to 1M. When blocks >1MB have been enabled
via the zfs_max_recordsize module option, this limit is increased
accordingly.
