LU-16053 build: Update zfs configure checks

From Brian Behlendorf <behlendorf1@llnl.gov>:

update dmu_*_by_dnode checks
 Provided as a feature since ZFS 0.7.0, convert to a fatal configure
 error when unavailable.

update zap_*_by_dnode checks
 Provided as a feature since ZFS 0.7.0, convert to a fatal configure
 error when unavailable.

update multihost protection check
 Provided as a feature since ZFS 0.7.0, convert to a fatal configure
 error when unavailable.  Drop the compatibility code required to
 support OpenZFS releases older than 0.7.0.

update userobj accounting check
 Provided as a feature since ZFS 0.7.0, convert to a fatal configure
 error when unavailable.

update dmu_prefetch() check
 Provided since at least ZFS 0.7.0, convert to a fatal configure

update dmu_object_alloc_dnsize() check
 Provided since at least ZFS 0.7.0, convert to a fatal configure
 error when unavailable.

update spa_maxblocksize() check

update dsl_pool_config_enter/exit check
 Convert to a fatal configure error, these functions have
 been provided since at least ZFS 0.7.x.

replace sa_spill_block() check
 The sa_spill_block() function was removed after the ZFS 0.6.x
 release.  Replace the check with one for use zio_buf_alloc/free
 which have been available since 0.7.x.

 The dsl_sync_task_do_nowait() function has not been provided
 by since the 0.6.x releases.  Furthermore, the results of this
 check are unused by Lustre so let's just remove it.
